Recommended Trailer Coupler Lock for Pole Tongue Trailer


Hello, I have an Aluma trailer with a straight tongue coupler. What do you have for a security lock when its not attached to the truck? I think some wont fit because of how far the latch travels forward.


Expert Reply:

I'd recommend a universal coupler lock set like the # DT25013KA from Fastway. The coupler lock is compatible with 1-7/8, 2 or 2-5/16 inch couplers.

I'd also go with a latch lock like # e98887 to prevent the coupler from coming unlatched while towing. It'll also prevent the trailer from being hitched up.
