Size and Type Bolts Required to Install Demco A-Frame Trailer Coupler with Hole for Trailer Jack  

Hey Robbie, A slight amount of wiggle room is necessary for a trailer coupler like the Demco #DM16680-52 you were looking at. If the latch mechanism is too tight then you wouldn't be able to get coupled to the hitch ball and the latch would…

I would be happy to help you. I recommend the Demco 50-Degree A-Frame Trailer Coupler w/ Jack Hole and Anchors, eZ-Latch - 2-5/16" Ball - 21K item #DM16680-52. The Demco eZ-Latch mechanism will give you a simple, secure hookup, and disconnect.…

The eZ latch of the Demco 50-Degree A-Frame Trailer Coupler w/ Jack Hole and Anchors, eZ-Latch - 2-5/16" Ball - 21K #DM16680-52 is absolutely just as safe as a slide lock coupler. It doesn't use a pin but still exceeds the SAE J684 safety…

The play you are feeling/hearing is most likely between the hitch ball and the latch of the coupler. If you look under the coupler you can see an adjustment bolt that uses an Allen wrench that will allow you to tighten the latch and get rid of the…

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…

Yes, the Demco coupler part #DM16680-52 is safe to use on a 31 foot air stream trailer like you have. Bolting on and welding on coupler is both perfectly safe to do. I would agree bolt on is easier in a sense but if you have a welder that route would…

You can absolutely wire up a 3-wire breakaway switch like the Hopkins LED Breakaway Switch with 7" Lead Wires #HM20059 to replace your 2-wire switch; the difference is that the 3-wire switch has a dedicated ground wire while the 2-wire switch…

The Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 3.5K #23-468-469 are not designed to be manually adjusted in the way you are describing. There isn't really a way to back off the adjustment because…

I recommend using Grade 5 1/2" x 4" bolts to install the Demco Channel Tongue Trailer Coupler part #DM12717. These would allow for the full weight capacity of the coupler to be achieved. These can be picked up at most local hardware…

Thanks for that photo, I do appreciate it. And all of the couplers we have - and indeed all the ones I am aware of - require a frame that is fully engaged. While Demco was not able to provide a dimensional drawing, we did measure the Demco 50-Degree…

Starting with the safety chains they really need to be attached to the trailer frame and not the coupler hardware. If there is no where to attach the chains on the trailer you can weld on safety chain mounting brackets such as #MB12, #MB38, or #MB58.…

Yes, so long as you have a standard a-frame trailer you will be able to replace your current welded on coupler with the Demco 50-Degree A-Frame Trailer Coupler w/ Jack Hole - eZ-Latch - Zinc - 2-5/16" Ball - 21K item #DM13205-95. I have attached…
