Do You Carry a Bolt On Trailer Jack Which Mounts to a Trailer Tongue With 2 Mounting Bolts Versus 3?

Question

Question:

I have a 1997 Trail-Rite boat trailer that I tow a 21 Striper with. The jack that came stock on the trailer has rotted on the bottom so its no longer stable. I have since mounted a side mount swing down jack but its not real stable. I would like to replace the original one but cant seem to find one that matches. Most I have seen have three mounting bolts in a triangular pattern where mine is two holes. I can provide photos if this is not clear.

All the bolt on trailer jacks we carry use the 3 bolt pattern which is commonly found on todays Couplers # DM14793-81. You may be able to replace your current jack with a Round A-Frame Trailer Jack # TJA-5000T-B. This will require a 2-1/4" hole opening for the jack to fit through as well as new mounting holes to be drilled into the mounting plate to secure the jack.

If you look at the diagram that I received from my contact at Demco, you can see several of the dimensions of the #DM14793-81 trailer coupler. If there were other dimensions you were needing, please let me know.

All of the A-frame couplers we carry are for the standard 50 degree A-frames. What you could do, since your A-frame is a lower angle, is have some steel spacers welded on to get to 50 degrees and then use a weld-on coupler. I have linked the weld-on…

A little bit of play is acceptable, the coupler should be tight enough that the coupler won't come off the ball, but not so tight you can't close the latch. I typically tighten the coupler up until I feel a slight resistance when closing the…

Generally the Demco A-Frame Trailer Coupler w/ Jack Hole part #DM14793-81 is very easy to release. There is a lock/pin hole located just under the latch that may have a pin in it preventing it from opening. I have linked a photo showing exactly where…

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 attaching the…

I went out to the warehouse to measure the Demco A-Frame Trailer Coupler #DM14793-81 that you asked about and found that it measures 3-1/2" from the bottom to the top. I have attached a picture to demonstrate. If your safety chains are welded to…

Only solution will be to extend out the frame rails of your trailer so that you can install a standard coupler on to them. None of the options out there are going to be large enough to fit your frame channels that basically start too far apart. What…

I went ahead and checked, and unfortunately there is not a coupler repair kit for your 2" Atwood coupler. With that being said, the best solution is going to be a full coupler replacement. I recommend checking out the: -Demco A-Frame Trailer…

Answer 9

Nearly all A-frame trailer have a 50 degree angle frame, the Demco A-Frame Trailer Coupler #DM14793-81 that you referenced has a 50 degree angle too. I would be surprised if your trailer had a different angle, but to be sure you could use an angle…

Answer 10

The Demco A-Frame Trailer Coupler w/ Jack Hole #DM14793-81 you were looking at features an "eZ-Latch mechanism" which will make coupling super easy. When you drop the trailer down onto the ball it will automatically latch and unlatching is…

Answer 11

Atwood was bought out and their replacement parts are no longer available - including the repair kit you mentioned - so the best option is to replace that A-frame coupler with a new one that attaches to a 2 inch hitch ball. There is a similar option…

Answer 12

It sounds like you need to replace your trailer coupler as there should not be excessive up and down or side to side play on the hitch ball. If you do have too much play or the latching mechanism is not functioning properly like you said then you are…
