I would use a protractor, see photo, place the protractor on the edge of the inside of one side of the trailer frame and the other inside edge of the trailer frame should be parallel with the 50 degree line on the protractor. Another way to verify…

We currently have three versions of the Demco 32 degree A-Frame coupler but none of them are zinc plated. We have the part #DM15633-97 which is primered, the part #DM15633-81 which is powder coated black, and we have the part #DM15633-52 which is…

The only differences between the Demco eZ-Latch Couplers #DM37ZR and #DM14793-81 is that the former has integrated loop holes for installing safety chains and a about a 2" drop while the latter doesn't come with provisions for…

I checked the Featherlite Trailer website for specs on the model 3116 trailer but this part number returned no results. But if your trailer uses an industry-standard 50-degree a-frame design then the Demco A-Frame Trailer Coupler #DM16680-52 will fit…

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…

The Bulldog Heavy-Duty A-Frame Coupler, #BD44150WH301, does not come with the attachment bolts. I have attached two images showing the bolt pattern measurements and the bolt hole sizes. I would recommend using grade 8 bolts, but grade 5 is acceptable…

Hi Larry, So we have a couple bumpers that may work, though each is 96 inches long. They can be cut to length though, and the difference is their width, as one is 3" wide and the other 4" wide to fit different size bumpers: - Pre-Drilled…

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 Replacement Shock Absorber Spring Kit #TK71-758-00 is the correct shock for your UFP Surge Brake Actuator. The picture you included does not specify if it is for a disc or drum brake set, so I have found both for you to choose from. Disc Brake…

Most A-Frame Trailer Couplers have a standard of 50 degrees. I produced a short video for you showing the angle of the etrailer A-Frame Coupler, part #CA5400. I have also linked an FAQ on trailer couplers.
