Video Transcript for Breaking Down the Coupler Pin

Howdy neighbor, Adam here with etrailer. Today, we're gonna be taking a look at a coupler pin. So we have a lot of these on our website, but some are gonna be better for other couplers than the others. So with this one, it's gonna be 3 1/2 inches long, and it's gonna have a diameter of about 1/4 inch. So make sure that your hole is gonna be nice and sized right so we can fit this on here. This is gonna be great for the easy lock couplers, as you see here, it's plenty long, and it is gonna be made of steel with a zinc coating, so it's not gonna rust away over time.

So it'll look good just like our powder-coated coupler here. And it is a little spring latch, you just lift this up and clip it in. You can use it on couplers like this, it might be a little overkill since it's so long. We really don't need a long one for this. We do have a shorter one we just did a video on, and that's on our website as well.

So it will work for this, but it's a little big. And that'll do it for our look at the zinc-plated 3 1/2 inch coupler pin..

I have a 2023 Airstream Globetrotter 25FBT with a Demco style coupler. This is the pin you need for coupler. You do need to bend the spring latch portion. F you have one of these couplers, you know what I mean. This coupler pin works with mods. Excellent service from etrailer.com, as usual. Photo is after I bent to fit Demco coupler.

Took a measured guess on which coupler safety pin would fit my new dump trailer, since I quickly lost the one that came with it.
The new one fits perfectly (I bought two just in case, lol). Came quickly in the mail. Love etrailer.com for their easy to use website, and great phone and email assistance (when needed)!



by:

I had a coupler ring with a round bail. My tail gate rested on the round coupler pin when fully lowered. This wide flat coupler allows me to feed the 7 pin trailer cord, the trailer video camera cord and the break away cord through the bail so all connections are lying flat. I can lower the tail gate and have about 3/4 inch clearance between the coupler and the tail gate.



by:

The coupler pin I got won't fit the new coupler. It looks like good quality, but the locking mechanism won't go around the new coupler.

  • Comparing Demco Channel Tongue Trailer Couplers # DM16080-95 & # DM15931-95
    The only difference in the Demco Channel Tongue Trailer Couplers # DM16080-95 and # DM15931-95 is going to be the bolt pattern. One will have the 5-Bolt hole pattern and the other is going to have 4-Bolt holes. I have included images below showing the measurements for each of these bolt patterns to compare with what you have on your trailer. The etrailer Surge Brake Coupler Lock # e98888 will allow you to secure the coupler while attached to your vehicle. We also have a Pin # 37201211...

  • Can The Lippert RV Spare Tire Carrier Winch Be Locked In Place To Prevent The Tire From Dropping?
    There is no way to lock the Lippert RV Spare Tire Carrier with Winch # LC159041 as it ships from the factory. You would need to weld on a tab which would allow you to use a Pin # 37201211 by drilling a hole through the tab and shaft for the winch. We do have a Replacement Winch # LC159056 you can use to replace your current winch since the internal brake is not holding the tire in place. Lippert does note with these to not over crank or use any power tools to raise/lower the tire as that...

  • Can Coupler Pin Be Added To Demco Trailer Coupler
    Yes, you can use a coupler pin or safety pin with the Demco Trailer Coupler # DM14040-81. A pin like the # 37201211 will fit the 5/16" pin hole or you can use the etrailer Surge Brake Coupler Lock # e98888 if you want even more security.

  • replacement Pin for an Old Thule Rac N Lock Carrier
    Do you have a way to measure the opening? For this purpose even a ruler would suffice in showing the diameter that would fit versus what would not. Pin # Y8780020 is a 3/8 inch diameter which is about as small as you are going to find for pins like this. Everything else is going to be 1/2 inch or larger. Outside of replacement bike rack parts we have snapper pin # 14-212TR which is a small 1/4 inch diameter. The same for # 14-238 and the longer # 37201211.

  • Trailer Coupler Safety Pin with At Least 3 Inch Span
    The best option we have for you is the Snapper Pin part # 14-212TR which is 1/4" diameter with a 2-1/2" usable span. The only option we have with both a 1/4" diameter and at least 3" usable length is the Trailer Coupler Pin part # 37201211 which has a square shaped bale, not the half moon shape you are after. If you would like a locking coupler lock we have the Trailer Coupler Lock part # e98888 which is 1/4" diameter with a 3-3/8" usable span.

  • Recommendation for a Handle Locking Pin on the Reese Titan 20k Sliding Hitch
    Good news, I was able to find 3 pins that will work for you. The Torklift Turnbuckle Pin Lock # TL11001, Roadmaster Coupler Padlock # RM-305, and the Husky Safety Lock Pin # 37201211 were the three pins I found that will fit through the hole in the handle. I tested all of these options and would recommend the # TL11001 because it was the easiest to insert and remove and is a locking pin. Alternatively, the Roadmaster Padlock was very tight and the Husky fit just fine but doesn't have...
