Video Transcript for Curt Hitch Pins and Clips - Standard Hitch Pin - F-4 Review

Today we'll be reviewing part number F-4. This is the Curt Class I and Class II Pin and Clip. It's going to give us a diameter of 1/2". This is designed for 1-1/4" x 1-1/4" hitch openings. The overall length of the pin is going to give us a measurement of right at 4". The amount of usable space that we have is from the pin hole to the curve. That's going to give us a measurement of 2-1/2".

It does come with a retaining clip. That way you can secure the clip on the other side of the pin. The way this works is you just, in your Class I or Class II hitch, after you get your accessory loaded up, you need to line up your pin holes, place the pin through one side of the hitch, through the accessory pin holes and out the other side of the hitch. Once you have that through you just simply take the clip and place it on the other side of the pin to secure everything in there and to make sure that your accessory is not going to come out of your hitch. It has this nice point tip. That way it's just an easier installation as you slide it through the pin holes. That's going to do it for today's review of part number F-4.

This is the Curt Class I and Class II Pin and Clip measuring 1/2" in diameter. .

This 1/2" diameter pin fits 1-1/4" square receiver hitches. Includes retaining clip. Zinc finish resists corrosion.


I got this a year ago to install on my tiny Honda Fit.It was easy to put together myself. I needed extra room to attend art fairs with all my product and displays. It works very well and so easy to take off and put it back on whenever I need to use it.


Excellent service, quick responses to questions and delivery


Arrived 1 day early. Will buy from etrailer agin


I ordered this part by accident I didn't notice it came with the hitch. I'm going to keep it. I have a bolt in one of my other vehicles.


Great product, tho directions called for 19mm socket (actually uses 18mm socket). Installed in my driveway using common tools, and drove the rear wheels up on some blocks of wood to get a couple extra inches of space to work. I loved the 'fishing wires' that came with to get the bolts and spacers through the holes - how clever!


like the stuff I;ve ordered so far!


Rcvd my hitch today (one day earlier than predicted by etrailer when I ordered...well done!). Everything was received as expected/requested.
Crawled under the car and started installation immediately. Piece of cake really; although some people would struggle with the tight space, 13 year old car, and need to clean threads, and remove caulk/undercoat in order to achieve "hole alignment".
Hyundai also did a great job by having pre-threaded welded nuts in place.
So far.... a great product received in time to use this weekend (as was my plan).

Great job and great product by etrailer.
Also, the website was easy to use and the videos quite helpful.
I will be back!
Thank you,
2008 Hyundai Sonata



Hitch etc is holding up fine. Routinely used to pull trailers up to 2000 lbs with a 2008 Hyundai Sonata. I avoid going over 55 mph, or sway is detectable.


Fits good and tight into the space available, and designed to take advantage of the strongest part of the unibody.
Pro tip #1: On Subaru installations calling for cutting out an opening, take the time to remove the bumper, allowing access to the unibody tunnel without hacking a hole into it, to insert the carriage bolts and reinforcement plates.
Pro tip #2: While you have access to the unibody tunnel, now is a great time to apply Fluid Film/Woolwax/B'laster Surface Shield to the interior of the unibody, bumper, and undercarriage, to make your automobile last much longer!


It’s a hitch pin, it worked great. I don’t leave my hitch on 24/7. I would recommend a locking hitch pin if you plan on leaving your hitch on permanently. I only use mine a few times per year, so this one was perfect.


I always seem to miss place the pins so I got extra, the personal at rtrailer are great, Tammie you did a great job, that's why I keep coming back

Les C.


Works great, Tammie did a great job,I will an have told my friends


It's a hitch pin. What could go wrong.

for the fine service and quick delivery.


The most straight forward install ever. Excellent instructions, four bolts and your done. The only thing you really need is a torque wrench. Well designed product and no interference with stock exhaust on my 2011 VW GTI.


Ended up not needing it because bike rack came with pin but good for a back up I suppose.


self explanatory.


As described, it's a hitch pin and clip for 1-1/4" hitches. Wow!


Both products I ordered were received within 2 days. Etrailer provided excellent communication throughout, letting me know who was responsible for overseeing my order and it's status.


Quick. Fair Price. Excellent Communication. First, we ordered the hitch and had it installed. Then we needed the perfect fit for the task at hand: to pull a tank with gray water through a campground. Very specific. Just for our toad, a Smart car. has the perfect software to lead you to what you need for the perfect combination. Quick shipment, reasonably priced. Direct communication for every step in the process. All in all, exactly what you’d hope for during these extremely dysfunctional time.


Well this install on my '05 Outback Wagon was more challenging than the last one I did on my '05 Baja but all's well that ends well. Haven't done the wiring yet because the hardware install took all day but confidence is high. These guys make a quality product!


I ordered parts for trailer hitch and lights a year ago. My car guys installed it apparently with no problem. There was no problem with my order and the product has worked just fine. The hitch has been used to pull a trailer and to hold a bike rack. I am pleased! Thanks!


I am so glad I decided to do this. I am a novice and it took my a little longer to install it but I had no issues. It is very sturdy and stable. This allowed me to install a lockable bike rack for mountain biking trips. I have been using this for 2 months now on 7 or 8 mountain bike outings and this hitch is solid. Great purchase. Well worth it.


Not much to say about a hitch pin.


Much easier to use than the threaded pin included with our hitch.


It does what is expected.


Every part excellent quality. Perfect fit, all parts were exact for my vehicle. Watched the video on youtube for wiring and being a mechanic for over 50 years was able to connect signal lights all from driver side of harness. Instead of leaving plug inside trunk I wired through the rubber outlet to the back of the hitch ready for use. Very happy highly recommend etrailer.

Brad H.


Very happy with products all high quality feel confident using. Thanks


I am very happy with the product

  • Does My 2020 RAM 3500 Have Non-Standard Hitch Pin?
    We have never seen an 1/2" diameter hitch pin on a 2-1/2" receiver. They all have 5/8" standard. We only see the 1/2" pins on the small 1-1/4" receivers. I would measure your hitch pin carefully. Is it possible that everything is 5/8" but just has a loose fit? Hitch parts do not have tight tolerances and tend to wiggle and rattle a little. Most likely your setup is just fine.If the rattling becomes annoying you can always add a Trailer Hitch Anti-Rattle Kit for 1-1/4" Trailer Hitches,...

  • Trailer Hitch For A 2014 Nissan Juke Midnight Edition
    We have just the trailer hitch for you. The Draw-Tite Sportframe Trailer Hitch Receiver # 24892 is confirmed to fit your 2014 Nissan Juke Midnight edition. The trailer hitch has a bolt-on installation with no welding required. It has a black powder coat finish that covers an e-coat base that offers a superior rust protection. The trailer hitch has a maximum tongue weight up to 200 pounds, but I would recommend checking your vehicle's manual to find out the proper tongue weight capacity...

  • Will the Curt Universal Fifth Wheel Base Rail Kit Work With a Reese 5th Wheel Hitch
    The Curt Universal Fifth Wheel Base Rails with Installation Kit part # C16200 will work with any Reese 5th Wheel Hitch that mounts to ISR rails. In regards to the pins used to secure the hitch to the rails, these come with the hitch but if you need them we do offer the Curt Hitch Pin and Clip part # F-4.

  • Pin and Clip That is 1/2 Diameter and 4 Long
    I'm not 100 percent sure what you mean by "latch pin or something" but I am assuming you mean a pin and clip, and we do have one that is 1/2" diameter and 4" long, the Curt Class I and II Pin and Clip # F-4. This pin and clip is a total of 4" long overall with a 2-1/2" long straight pin. The 1/2" diameter is standard for a hitch pin and clip for a 1-1/4" receiver so the straight part of these is not going to be as long. If you were looking for a hitch lock the longest with a 1/2" diameter...

  • Best 1/2 Inch Hitch Pin that is Long Enough to Fit a 2 Inch Hitch Receiver
    Is there a threaded nut inside the shank of the bike rack? My guess is that is the case. I would need to know the bike rack manufacturer and the model though the model is not as important as the manufacturer. If you can tell me that information I can determine if we have the proper threaded hitch bolt for that rack. If it does not have a threaded hitch pin hole and the issue is length you can use the Curt Clevin Pin with Handle # C45805. This pin has a 6-7/8 inch usable span so it is plenty...

  • Hitch Pin to Use with Curt Hitch # C12264
    Hitch pin size doesn't matter that much I would say. As long as the pin fits through the hitch pin hole and the accessories hitch pin hole you'd be fine. That said, if you were looking at the Curt hitch part # C12264 the # F-4 is an easy solution for a hitch pin and clip.

  • Why Does my 2 Inch Hitch have a 1/2 in Pin Hole and a 5/8 in Pin hole
    The Curt Pin and Clip # F-4 that you referenced is designed to work on 1-1/4 inch hitches. The reason your hitch has a 1/2 inch hole and a 5/8 inch hole is because it is setup for an obsolete anti-rattle device Draw Tite J-Pin. We no longer carry the J-Pin so that hole is no longer used. This 1/2 inch hole is not designed to be use as a hitch pin hole, you will want to use 5/8 inch pin and clip like the # PC3.

  • Will The Alpena Trailblaze LED Lights Interfere With The BLIS System On My 2018 Ford F-150
    I emailed Alpena to get some clarification on their Alpena Trailblaze Tailgate LED Lights, part # ALP77229. I was told that the placement of the LED lights will not block or interfere with the BLIS sensors. However, the newer model years of the Ford trucks, may think that a lightbar is really a trailer when they are hooked up to the 4-way connector due to the power draw of the lights. Alpena has not seen that be an issue with the Trailblaze Tailgate LED Lights, but the lights were launched...

  • What is the Size of the Hitch Pin that Comes With the Curt Trailer Hitch Receiver C11276
    The Curt 1-1/4 inch Trailer Hitch Receiver # C11276 that you referenced is a confirmed fit for your 2014 Toyota Prius Plug-in Hybrid and comes with a 1/2 diameter hitch pin that can be found with part # F-4. Keep in mind that you will need to use a Support Strap # 18050 for any non-trailer loads like a bike rack or cargo carrier when using this hitch per the Curt Warranty. I have attached a video of this hitch being installed on a 2014 Prius for you to reference.

  • Hitch For A 2018 Ford Fusion Sedan
    Your 2018 Ford Fusion is a Sedan model which I recommend the Curt Trailer Hitch Receiver Item # C12091. This hitch has a 1-1/4" receiver tube openings with a 350lb tongue weight rating and a 3500lb trailer weight rating. The hitch pin hole is a 1/2" in diameter and does not come with pin and clips. Most bike racks come with pin and clips or anti rattle devices however; if you were planning on pulling trailer you would need Curt Class I and II Pin and Clip Item # F-4. If your vehicle was...

  • What Hitch Receiver do You Recommend on My 2022 Toyota Camry Hybrid?
    For a great hitch for your 2022 Toyota Camry Hybrid, I recommend the Curt Trailer Hitch Receiver - 1-1/4" # C11576. Apart from providing your vehicle with 200 pounds of maximum tongue weight and 2,000 pounds of maximum towing weight capacity, it is also assembled here in the U.S.A. It is always important to confirm with your owner's manual to make sure your Camry can withstand that much weight. This hitch is confirmed to fit all hybrid Camry models (LE, SE, SE Nightshade, XLE, and XSE). If...

  • Recommended Ball Mount and 2" Hitch Ball for 2019 Volvo XC60
    I took a look at the factory hitch for a 2019 Volvo XC60 and it appears that it will use a euro ball mount, the Curt Class II Euro Style Drawbar part # C45572 with Curt Class I and II Pin and Clip part # F-4. If you don't think this will work, please send photos of your setup so I can better understand the issue you are having.

  • Can Hole be Drilled in Trailer Hitch to Align With Ball Mount
    I do not recommend drilling a hole in a trailer hitch like the Draw-Tite # 76154 that fits a 2019 Nissan Titan as not only will this void the warranty but hitches have not been tested to be used after modification. A Class III, 2" hitch like the Draw-Tite is designed to be used with a 5/8" diameter pin and clip such as # PC3, while a 1-1/4" hitch will use a 1/2" diameter pin and clip like # F-4.

  • Ball Mount for 1-1/4 Inch Receiver With 50mm Hitch Ball
    The Curt Class II Euro Style Drawbar with 1-7/8" Ball # C45591 will fit a 1-1/4 inch trailer hitch receiver and secure to the hitch with Pin and Clip # F-4 but I wouldn't be able to tell you if it will fit a European trailer. It has a 1-7/8 inch hitch ball so it's not exactly the same size as a 50mm hitch ball. That said we do offer a 1-1/4 inch ball mount and 50mm hitch ball that will fit together: - Draw Tite Drawbar for 1-1/4" Hitch # 36053 The Draw-Tite does come with a pin and clip...

  • Ball Mount to Use with Class II Hitch Towing Small Trailer
    Best option would be a ball mount that fits your Class II hitch directly and not to use a hitch adapter as they cut the capacity of the hitch by 50 percent. We have the Euro style Class II ball mount with part # C45551 which has a 1-7/8 inch hitch ball and a 2-3/4 inch rise. We also have a pin and clip with part # F-4 to use to secure the ball mount to the hitch.

  • Compatibility of Curt Class II Drawbar # C45521 With OEM 1-1/4 Inch Receiver on 2012 Ford Escape
    The Curt # C45521 drawbar you referenced is compatible with a 1-1/4 inch receiver, as is the # F-4 hitch pin and clip. You'll want to make sure that the hitch on your Escape has sufficient capacity to handle the pop-up you're planning on towing. The first thing I'd recommend you do is to determine the capacity of the hitch. The hitch should have a sticker on it telling you if it's a Class I or a Class II hitch. A Class I hitch will have a towing capacity of up to 2000 lbs, and a tongue...

  • Do I Need to Drill a Hole in a Draw-Tite Hitch for More Room for a Hitch Pin?
    I have a solution for you but you do not want to drill a larger pin hole on your X1's Draw-Tite Hitch item # 75761. This will void your hitches warranty and lead to premature rusting. Instead you will want to use the etrailer Trailer Hitch Lock item # e98879. This pen is still a 1/2" diameter but it will go in better than a standard pin like item # F-4. Plus this is a locking hitch pin which will allow you to secure your bike rack and any other accessories. If you don't like this option...

  • Hitch Pin or Locking Hitch Pin for 1-1/4 Inch Trailer Hitch Receiver
    For a 1-1/4 inch trailer hitch receiver the hitch pin size needed is 1/2 inch diameter. Whether it is a Class I or Class II trailer hitch like the Draw-Tite # 36524 you mentioned, you will use the same size pin and clip like # F-4. If you would like a locking hitch pin for this size hitch receiver, my favorite is the Trailer Hitch Receiver Lock for 1-1/4" Hitches # e98879.

  • What Adapter Do You Recommend for Making a 1-1/4 Inch Hitch Take a 2-Inch Accessory?
    For this issue, I recommend the Hitch Adapter 1-1/4" to 2" Trailer Hitch Receiver # HTAD. From the pinhole to the end of the part that is inserted into the hitch receiver is just under 1-1/2 inches. We have had other customers with 2021 Volvo XC60s confirmed that the length issue was bypassed by this receiver. In order to know if it will work for sure with your hitch receiver, I recommend that you insert a tape measure into the hitch receiver and measure the length from the backstop to...

  • Does Curt Trailer Hitch # C45014 Come with Hitch Pin
    The Curt hitch part # C45014 does not normally come with a hitch pin. I realize that seems odd since it does come with a ball mount but you'd need to provide either a hitch pin or hitch lock. For a hitch pin you'd want the part # F-4 or for a lock part # e98879.

  • What Hitch Pin Do I Need for the Draw-Tite # 24960 and # 76209 for a 2021 Subaru Impreza?
    If you are looking at the Draw-Tite # 24960 (sedan models only), you will need a hitch pin that is compatible with a 1-1/4 inch receiver. For that part, you need the Curt Hitch Pin and Clip for 1-1/4" Hitches # F-4. As for the Draw-Tite # 76209 (5-door wagon with single exhaust models only), you will need a hitch pin that is compatible with a 2-inch receiver. For that part, you need the Pin and Clip for 2" # PC3.
