C.E. Smith Brass Coupler Lock

The C.E. Smith Brass Coupler Lock (part number 00900-40) is a precision-engineered security device designed for boat trailer coupling systems. This locking coupler provides essential theft deterrence and peace of mind when your trailer is parked or unattended, making it suitable for weekend boaters and fleet operators alike.

Constructed from brass, the C.E. Smith Brass Coupler Lock resists corrosion and degradation in marine environments, where standard steel locks may fail. The reliable locking mechanism engages the coupler ball to prevent accidental or intentional separation, requiring a key to disengage. This design ensures that the lock is effective in protecting your trailer from theft.

Trailer owners benefit most from this lock when securing trailers at boat ramps, storage facilities, or job sites. Installation requires no modifications to standard coupler setups; the lock fits over the ball coupler and locks into position. While it is designed for compatibility with standard ball couplers, users should verify compatibility with their specific coupler type.
