Application-specific stainless steel trailer latch lock for Dexter A-60 2" ball couplers, designed to secure compatible weld-on or bolt-on marine trailer coupler latches.
The InfiniteRule 61199-S is designed for Dexter A-60 trailer couplers that use a 2" hitch ball. It helps secure the coupler latch mechanism so the latch cannot be easily opened or tampered with while the trailer is parked, stored, or left unattended.
This lock is especially relevant for marine and boat trailer applications where Dexter A-60 couplers are commonly used. Its CNC-machined stainless steel construction helps resist corrosion, wear, and outdoor exposure, while the weather-resistant cap helps protect the lock core from road grime, water, and salt.

InfiniteRule 61199-S is for compatible Dexter A-60 couplers with 2" ball fitment. It should not be assumed to fit all Dexter couplers, all surge brake actuators, all marine trailer couplers, trailer doors, RV compartments, storage gates, receiver hitches, or universal latch applications. Verify the coupler brand/model, A-60 identification, 2" ball size, weld-on or bolt-on coupler style, latch shape, lock point, span, and lock clearance before ordering.
Before Starting: Confirm the trailer uses a compatible Dexter A-60 2" ball coupler and that the latch lock point matches this InfiniteRule lock. Inspect the coupler, latch, actuator, and lock area for rust, deformation, damage, or misalignment before installing the lock. Basic Use Steps: 1. Park and Secure Trailer: Park on stable ground, chock wheels, and make sure the trailer is safely supported before installing a security lock. 2. Close the Coupler Latch: Make sure the Dexter A-60 coupler latch is fully closed according to the coupler manufacturer’s instructions. 3. Align Lock Point: Locate the latch lock opening and confirm the lock can pass through without forcing the latch or actuator components. 4. Install Lock: Insert the latch lock through the compatible lock point and secure the locking end with the supplied key. 5. Check Latch Security: Gently test the latch to confirm it cannot open while locked. 6. Install Weather Cap: Seat the weather-resistant cap to help protect the lock core from dirt, water, salt, and grime. 7. Store Keys Safely: Keep spare keys in a secure location and record the key number if provided. 8. Remove Before Towing if Required: Follow the trailer, coupler, and lock manufacturer’s instructions before coupling and towing.
Package Contents: • 1 InfiniteRule 61199-S trailer coupler latch lock • Stainless steel lock body / locking pin assembly • Weather-resistant cap • Keys as supplied by manufacturer or distributor packaging NOT Included — May Also Need: • Dexter A-60 coupler or actuator • Full coupler surround lock • Receiver hitch lock • Trailer door or compartment lock • Safety chains, breakaway cable, or towing hardware • Replacement coupler latch parts • Surge brake actuator repair components This listing is for the trailer coupler latch lock only unless otherwise stated. Confirm Dexter A-60 2" coupler compatibility before ordering.
To confirm compatibility before ordering, have the following ready: • Trailer coupler / actuator brand and model • Confirmation that the coupler is a Dexter A-60 • Coupler ball size, specifically 2" for this lock • Whether the A-60 coupler is weld-on or bolt-on • Photos of the coupler latch in the open and closed positions • Photos of the latch lock point and surrounding actuator area • Whether you need a latch lock, full coupler lock, receiver lock, or door/compartment lock Why this matters: InfiniteRule locks are application-specific. Similar trailer couplers and surge brake actuators may require different latch locks, spans, or lock styles.
Match this lock by Dexter A-60 coupler model, 2" ball size, latch style, lock point, clearance, and storage environment. Do not select it as a general trailer door or compartment lock.
If fitment or locking issues continue, check Dexter A-60 identification, 2" ball size, latch shape, lock point, actuator clearance, key operation, and whether a different InfiniteRule lock model is required.
This latch lock is a theft-deterrent accessory and does not replace proper trailer coupling or surge brake inspection procedures. Always confirm the Dexter A-60 coupler is correctly latched to the hitch ball, safety chains are attached, brake actuator/breakaway system is working if equipped, and all towing components are properly rated before travel. Do not tow with a damaged, mis-sized, loose, or improperly installed latch lock or coupler assembly.
