REESE Trailer Hitch and Coupler Lock Set — High-Visibility Yellow, Fits 1-1/4" & 2" Receivers, 1/2"–5/8" Pins

This combo pack pairs a universal trigger-release coupler lock, a brass coupler lock for use when attached to the tow vehicle, and a dual bent-pin receiver lock to secure ball mounts in both 1/2" and 5/8" applications. The locks are finished in a high-visibility yellow to act as a visual deterrent and are built for heavy-duty trailer use. Two keys are included so you can operate the set immediately out of the box.

How does the REESE combo lock protect my trailer when it’s parked?

The universal coupler lock closes over the trailer coupler to prevent a hitch ball from being inserted, rendering the trailer unusable to opportunistic thieves. Its bright yellow housing increases visibility so your trailer stands out, discouraging tampering.

• Trigger-release coupler lock with adjustable span 0.625"–1"
• Prevents ball insertion and secures the coupler latch
• Durable finish resists wear while remaining highly visible

Can I lock the trailer while it’s hooked to my tow vehicle?

Yes—the included brass coupler lock allows you to lock the coupler even when the trailer is coupled to your vehicle. This is useful for added security during overnight stops or storage when the trailer remains connected.

• Brass construction for reliable locking when attached
• Fits common coupler shapes and latch configurations
• Works alongside the receiver lock for complete coverage

Will this set fit my hitch receiver and ball mount pins?

The dual bent-pin receiver lock is designed to accept both 1/2" and 5/8" pin diameters, so it secures a wide range of ball mounts without needing multiple locks. It secures the ball mount to the receiver and helps prevent removal of the ball or mount while parked.

• Dual bent-pin design fits 1/2" and 5/8" pins
• Secures ball mount to 1-1/4" and 2" square receivers
• One set of keys operates all included locks

How durable and visible is the lock set for long-term use?

The locks are engineered for trailer environments—exposed to road grime, sunlight, and outdoor storage—and finished in a bright deterrent yellow to remain noticeable. Materials and construction focus on practical durability rather than being purely decorative.

• High-visibility yellow finish acts as theft deterrent
• Sturdy components intended for towing and storage use
• Corrosion-resistant elements where practical for outdoor use

Who this is for: The REESE Towpower 7014700 combo lock set is aimed at trailer owners who want a simple, practical security solution for travel trailers, utility trailers, and other towed equipment. It suits RV owners, landscapers, contractors, and anyone who parks trailers in public or storage where an obvious, mechanical deterrent reduces risk of unauthorized hitching or theft.
