Three-pack stainless steel keyed lock set for compatible Curt 2.5" adjustable channel mount hitches, including two hitch locks and one receiver lock.
The InfiniteRule 61801-S is a three-piece hitch and receiver lock set designed for compatible Curt 2.5" Adjustable Channel Mount / Curt 20K Channel Mount adjustable hitch applications. It includes two hitch locks for the adjustable channel mount portion and one receiver lock for securing the hitch shank in a compatible 2.5" receiver.
This set is meant to secure the major lock points on the matching Curt adjustable channel mount setup. The two hitch locks use 5/8" diameter pins with 4-1/8" spans, while the receiver lock uses a 5/8" diameter pin with a 3-1/8" span. It should not be treated as a generic RV tow hitch lock kit without confirming the Curt hitch model and lock locations.

InfiniteRule 61801-S is listed for use with compatible Curt 2.5" Adjustable Channel Mount / Curt 20K Channel Mount adjustable hitch applications and a 2.5" receiver. It is not a universal RV hitch lock set, trailer coupler lock, door lock, latch lock, or generic 2" receiver kit. Verify the Curt hitch model, receiver size, pin diameter, hitch lock spans, receiver lock span, shank size, adjustment channel width, and lock-head clearance before ordering.
Before Starting: Confirm the hitch is the compatible Curt 2.5" adjustable channel mount / 20K channel mount application and that the receiver setup requires a 5/8" pin with a 3-1/8" span. Inspect the hitch, receiver, adjustment holes, and shank holes for damage, rust, deformation, or misalignment before installing the locks. Basic Use Steps: 1. Install Hitch Shank: Slide the compatible hitch shank fully into the 2.5" receiver and align the receiver pin holes. 2. Secure Receiver Lock: Use the included 5/8" x 3-1/8" span receiver lock to secure the hitch shank to the receiver when the span and clearance match. 3. Set Hitch Height: Position the adjustable channel mount/ball mount at the desired height according to Curt’s instructions. 4. Secure Hitch Locks: Use the two included 5/8" x 4-1/8" span hitch locks in the compatible adjustable channel mount lock points. 5. Confirm Lock Engagement: Make sure all lock heads are fully seated and secured with the key. 6. Install Dust Covers: Seat the non-locking dust covers to help protect the lock cylinders from water, dirt, and road grime. 7. Inspect Before Towing: Confirm the hitch, receiver, ball mount, and locks are properly installed and rated for the towing setup. 8. Store Keys Safely: Keep spare keys in a secure location and record the key number if provided.
Package Contents: • 2 InfiniteRule 5/8" hitch locks with 4-1/8" spans • 1 InfiniteRule 5/8" receiver lock with 3-1/8" span • Keyed lock assemblies • Non-locking dust covers • Keys as supplied by manufacturer or distributor packaging NOT Included — May Also Need: • Curt adjustable channel mount hitch • Trailer hitch receiver • Hitch ball or ball mount platform • Trailer coupler lock • Trailer latch lock • Anti-rattle device • Safety chains, wiring, or towing hardware This listing is for the three-piece hitch and receiver lock set only unless otherwise stated. Confirm the exact Curt hitch model, receiver size, pin diameter, and required spans before ordering.
To confirm compatibility before ordering, have the following ready: • Curt hitch model and weight rating • Whether the hitch is a Curt 2.5" Adjustable Channel Mount / Curt 20K Channel Mount application • Receiver size, specifically whether the setup uses a 2.5" receiver • Pin diameter at each lock point • Required span for the two hitch adjustment lock points • Required span for the receiver lock point • Photos of the hitch adjustment holes and receiver pin hole area • Whether you need a hitch adjustment lock, receiver lock, coupler lock, or trailer latch lock Why this matters: This kit includes two hitch locks and one receiver lock with different spans. Using the wrong lock in the wrong location or ordering for the wrong hitch model may cause fitment or safety issues.
Match this set by Curt adjustable channel mount hitch model, receiver size, pin diameter, lock span at each location, and lock-head clearance. Do not select it as a universal RV tow hitch security kit.
If fitment or locking issues continue, check the Curt hitch model, receiver size, pin diameter, lock span at each location, lock-head clearance, and whether a different InfiniteRule kit is required.
Always confirm the hitch locks, hitch receiver, adjustable ball mount, hitch ball, trailer, and towing vehicle are properly rated and compatible for the towing setup. These locks help secure compatible hitch components, but they do not increase towing capacity, correct an overloaded trailer, replace safety chains, or fix an improperly matched towing system. Inspect all locks before each trip and do not tow with damaged, mis-sized, loose, or improperly installed towing hardware.
