Trimax UMAX50 Premium Universal 'Solid Hardened Steel' Trailer Lock (fits all couplers) Review

Average Reviews:

(More customer reviews)I bought the Trimax "Universal" lock only to find it was not universal. When attached to a Brenderup horse trailer's coupler, it would slide off over the front or simply fall off if the coupler lever was raised. The lock seems to require a groove on the top of the coupler to hold the lock's top bar-loop. Else, as on my trailer, it will not stay attached. It seems solid and may work for some trailers, but not for all.

Instead, try the Master Lock Universal Trailer Coupler Lock #377DAT; it worked for me and seems as if it will work for all couplers. Also it's $18 with free shipping instead of $36 plus $10 shipping for the Trimax.

That said about this product and it's inaccurate billing, I am happy with Mobile Mart who refunded my costs and paid for return shipping the lock.
