This is a universal trailer coupler lock manufactured by Trimax. This is Trimax’s part number UMAX50. This is a great lock to protect your boat trailer, utility trailer, enclosed trailer, or camper while it is parked unattended. This trailer hitch lock fits all three size balls (1 7/8”, 2”, and 2 5/16”). Trimax’s universal lock has a dual ratchet lock system that clamps down on a hardened steel 5/8” thick steel shackle. The key hole has a rubber cover that seals out dirt and grime.  The body has a rust proof hammer tone epoxy corrosion resistant finish.  The body is designed and shaped to help deflect hammer blows to the lock. The key hole uses a 7 pin high security lock that resists attempted drill outs. The key will not bend or break. This lock will fit couplers from Fulton, Atwood, UFP, Bulldog, Titan and many more. Installing this lock on your trailer coupler is easy! All you have to do is slide the ball on the lock up into the coupler and close the lever. Then simply push the hardened steel shackle down tightly through the lock housing and turn the key.
