The coupler lock secures trailer couplers sized at 1-7\/8 inches, 2 inches, and most 2-5\/16 inches. The receiver lock uses a push-to-lock mechanism — the lock body presses firmly onto the receiver pin and the key is removed to secure it, fitting both 1\/2 inch and 5\/8 inch receivers. The latch lock adjusts across six positions from 9\/16 inches to 2-3\/4 inches, covering a wide range of coupler latch sizes. This set is installed by fleet managers, transport operators, and service professionals who need coordinated trailer hitch security across multiple lock types.\u003c\/p\u003e\u003cp\u003eThis combo set is suited for use on tow vehicles and trailers in both residential and light commercial fleet applications. The three lock types work together to secure the full hitch assembly — from the ball coupler to the receiver tube to the latch mechanism. The keyed-alike configuration allows a single key to operate all three locks, reducing key burden during daily hook-up and release operations. The adjustable latch lock provides flexibility across varying coupler latch gap dimensions, making the set adaptable to multiple trailer types in a mixed fleet.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCoupler lock fits 1-7\/8 inch, 2 inch, and most 2-5\/16 inch couplers\u003c\/li\u003e\n\u003cli\u003ePush-to-lock receiver lock fits both 1\/2 inch and 5\/8 inch receivers — no tools required to lock\u003c\/li\u003e\n\u003cli\u003eAdjustable latch lock with six locking positions from 9\/16 inches to 2-3\/4 inches\u003c\/li\u003e\n\u003cli\u003eAll three locks are keyed alike for single-key operation\u003c\/li\u003e\n\u003cli\u003eCombo set ships as a package of 2 units\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe coupler lock fits 1-7\/8 inch, 2 inch, and most 2-5\/16 inch couplers.

Power down or disconnect any trailer lighting before servicing trailer hitch hardware. Verify that the coupler lock fully engages around the ball coupler before releasing the tow vehicle.
