This is a universal trailer coupler lock manufactured by Trimax.  This is Trimax’s part number UMAX100.  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 cover that slides up and down to seal out dirt and grime.  The ballistic grade nylon housing helps to deflect and absorb 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.
