will this fit a 4 wide coupler


Expert Reply:

I spoke with my contact at Master Lock about the Trailer Coupler Lock # 3784DAT. They were not certain if the lock is compatible with a 4 inch wide coupler. But, we do have other options. I have compiled a list below of the trailer coupler locks that will fit a 4 inch wide coupler.

Fastway Universal Trailer Coupler Lock, # DT25013KA
Trailer Coupler Lock, Gorilla Guard, # 63227 (for 2-5/16 inch couplers)
