LOCKED WHEN YOU LEAVE. LOCKED WHEN YOU SLEEP.

Slide it over the coupler. Pin it shut. Pocket the keys. Heavy-duty powder-coated steel core deters thieves — no bolt cutters, no pry bar, no quick drive-off from your driveway. Built for the RVer, the boat owner, the contractor who parks the dump trailer at the job site overnight.

MATCHED TO YOUR COUPLER. LOCKED FROM ANYONE ELSE'S TRUCK.

The four kinds of trailers thieves walk off with — covered. Fits any 2-inch standard coupler up to 3¾" lip width and ⅜" lip height: utility trailers, RVs, boat trailers, and off-road trailers. Slides over the ball socket and locks shut with the included keyed pin — same key, two locks. Check your coupler dimensions before ordering: doesn't fit Airstream Basecamps or oversized hitches. Lifetime warranty on the powder-coated steel core.

TESTED BY THE PEOPLE WHO ACTUALLY USE IT

Say goodbye to the guesswork of trusting a no-name import. With USA-built construction, your lock is field-proven by RVers, overlanders, and outdoor pros — from Baja switchbacks to Alaska winter parking, from boat ramps to construction sites.

Testimonials

★★★★★

"Drove a 32 ft Jayco from Texas to Yellowstone for a 3-week loop. Spent 7 nights at rest stops and Walmart lots. Locked the coupler every single time — slept easy. Came back, the lock still worked smooth after 4,200 miles of salt, rain, and dust."

"Park my bass boat trailer in the marina lot 3 nights a week. Two trailers got jacked from that lot last summer — neither had a lock. Mine's been sitting there with the RhinoGear on it since April. Still locked. Still my trailer."

"Leave my 16-ft enclosed work trailer at the site every night with $8K in tools inside. Used to drag it home daily. Two months on this lock and I sleep at home. Steel core, two keys, same lock cylinder — nobody's getting it off without a torch."

FAQs

Fits any 2-inch standard coupler with up to 3¾" lip width and ⅜" lip height — utility trailers, RVs, boat trailers, off-road trailers. Doesn't fit Airstream Basecamps or oversized hitches. Measure your coupler before ordering.

Heavy-duty powder-coated steel core, hardened cylinder lock. Won't pop with bolt cutters or pry bars. A determined thief with a cutting torch could eventually get through — like any lock — but it takes long enough that they move on to easier targets.

Yes. Same key cylinder for both the coupler housing and the padlock. Two keys included. Tuck a third in your truck's spare-key spot so you're never locked out at the trailhead.

Email us a photo of your order receipt. We mail replacement keys within 5 business days. We keep your lock's cylinder ID on file for the lifetime of the product.
