Does Latch of Demco Trailer Coupler DM15945 Require Initial Adjustment  

Updated 07/21/2025 | Published 12/20/2021

Question:

Hi, I just ordered the DM15945 trailer tongue. Do I need to adjust any kind of tension on coupler like the nut on the spring, or just mount it right out of the box and go? Bought a used trailer once and it popped off my trailer ball while I was going down the road. It had too much slack on the actual coupler part, and when I went over a bump in the road...

The latch of the Demco Channel Tongue Trailer Coupler # DM15945 that you referenced is pre-adjusted to fit a 2 inch ball as-is and would not require you to do any initial adjustments for it to work properly.

There is a lot of play with mine. How can I adjust it?

@Seth If there's play in the hitch ball you can use an allen wrench to tighten up the latch of the coupler from the underside.
