Hey John! We do have a lock for your Demco Channel Tongue Trailer Coupler # DM15945. Since this is a stamped 2" coupler you can use the InfiniteRule Trailer Latch Lock for Stamped Demco eZ-Latch Trailer Coupler # IR92FR.

This is the best option, and is specifically made for this coupler. It also has a stainless steel construction so you don't have to worry too much about corrosion. You can also use a more universal lock like our etrailer # e98887.

What kind of trailer do you have?

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.…

It sounds like you are speaking of the wires for the brake magnets. If this is correct, you will need to connect one of the wires to the brake controller output wire on your trailer connector and the other wire will need to be grounded to a clean…

Answer 8

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…
