Video Transcript for Curt Hitch Pins and Clips - Standard Hitch Pin - C21403 Review

Today, we're going to be taking a look at Part Number C21403. This is a Curt Class I and Class II pin and clip. It's going to have a diameter of 1/2 inch. The 1/2 inch diameter pin is going to secure your ball mount and accessories to your trailer hitch. This pin is decided for 1 1/4 by 1 1/4 square receiver style hitches. Here on the end of the pin, you're going to see a nice little grooved indention.

This is going to enable easy clip installation and removal. Again, the clip is included. Once you have it through your hitch and your accessory, all you've got to do is place that clip on the other side of the pin and it's going to secure everything inside of the hitch. This is made from steel construction. It has a nice zinc finish, so it's designed to stand up really well against rust and corrosion. We'll take a measurement of the overall length, measuring from end to end.

This is going to give us a measurement of about 3 3/4 of an inch. The measure of just the straight part of the pin, so measuring from the base of that curve to where the clip installs, that's going to give us a measurement of 2 1/4 of an inch. That's going to do it for our review of Part Number C21403. This is a Curt Class I and Class II pin and clip. .

I am thrilled with the trailer ball & hitch I purchased from you one year ago for my Toyota Camry. I have used the hitch numerous times to rent U-Haul trailers rather than trucks (which you have a mileage fee on) and saved more than triple the cost of my purchase. As the mom to a college aged daughter, I was the one to help her & her friends move out of the dorms, into their first shared apartment & delivered the gently used furniture we found online to furnish their first digs. Most recently I helped them move to a furnished shared flat and was able to haul their furniture to both a consignment store & a donation center so that their finds can live on and make other families happy. The products I purchased from etrailer.com still looks and perform like new. Thank you, Erica, for your professional advice and support. I highly recommend etrailer.com to everyone I meet! Sincerely, A grateful Mom

Replaced a missing pin on utility trailer ramp ... this one fit perfectly! Others were either too short for the span or were smaller in diameter, so they would fit loosely.

Excellent service and support. Hally was very helpful.

Okay. This is a very simple retaining pin. It would have to be an epic fail not to garner 5 stars. So far, that has not happened. :)

  • What Diameters Are Available For Hitch Pins
    Hitch pins come in 1/2 inch and 5/8 inch diameters with the 5/8 inch being the most common. Since it sounds like your hitch pin hole has elongated, you should get a new hitch. Send me the make, model, and year of your vehicle and I will make a specific recommendation. For a 1/2 inch diameter hitch pin, I recommend the Curt Class I and II Pin, Item # C21403, for a basic pin or the Tow Ready Trailer Hitch Pin, Item # TR63254 if you need one that locks.
