Master Trailer Coupler Lock

Master Lock - Model # 379DAT
This coupler lock is Master's newest version of the model #379. The interior of this lock is solid steel and then shrouded with a plastic - this permits Master Lock to incorporate a keyway cover to protect the lock from the elements.
The lock protects unattended trailers and guards against tow-away theft. It fits 1-7/8", 2", & 2-5/16" couplers by Reese, Fulton, Valley, Atwood, Shelby, Putnam, Hammerblow, Dutton, Lainson, and UFP.
Single Key Included!
