NUOVEPE Trailer Hitch Lock 2-5/16" Coupler Lock with Integrated Chain Capture — Heavy-Duty, All-Weather Security

NUOVEPE 2 5/16" Trailer Hitch Lock is a heavy-duty, all-weather coupler lock that simultaneously secures the trailer ball socket and safety chains with a single one-click mechanism.

Built for haul professionals, boat owners, and anyone storing trailers outdoors, this lock combines reinforced steel housing with a sealed brass core and an integrated chain capture. The unit fits most 2-5/16" trailer couplers and is made to slow down or deter smash-and-grab theft attempts while standing up to rain, salt, mud, and road grime. It reduces exposed pry points and eliminates the common gap thieves target between coupler locks and loose safety chains.

How does this hitch lock keep both the coupler and safety chains secure?

NUOVEPE’s dual-defense design slides an inner mechanism into the 2-5/16" socket, while an integrated ball-mount pocket captures and locks the safety chains to the coupler assembly. With one solid push-to-lock action, the lock creates a unified barrier that minimizes exposed chain sections and potential pry leverage points.

• Inner mechanism fits into 2-5/16" couplers to prevent tongue separation.
• Integrated chain mount locks chains against the coupler body.
• One-click puck-style locking eliminates loose parts and alignment hassles.
• Reduces exposed gaps that bolt cutters or pry bars exploit.

What materials and security features resist theft attempts?

This lock uses armor-grade, heat-treated steel for the outer shell and a precision-machined sealed brass cylinder internally. The housing resists impacts and cutting, while the brass core includes anti-pick grooves, hardened pins, and a drill-resistant design to increase time and noise required for forced entry.

• Heat-treated steel housing resists prying, hammer blows, and cutting.
• Sealed brass core with anti-pick and drill-resistant pins.
• Powder-coated exterior prevents corrosion and reduces shine to avoid detection.
• Sealed keyway helps block moisture, salt, and dust from binding the lock.

Will this lock survive harsh outdoor environments and frequent use?

Yes—NUOVEPE combines a durable powder coat finish with a fully sealed lock core to resist salt spray, rain, snow, mud, UV and road debris. The design targets year-round reliability so owners who launch boats, haul equipment, or park trailers in open lots can expect fewer maintenance headaches and smoother operation in cold or humid climates.

• All-weather powder coating reduces corrosion and finish wear.
• Sealed brass core prevents water and grit infiltration.
• Built for frequent daily use with a quick push-lock action.
• Five heavy-duty keys included to distribute spares and backups.

How easy is it to install and use during regular trailer operations?

Installation takes seconds: confirm coupler compatibility, slide the inner piece into the 2-5/16" socket, seat the safety chains against the integrated ball mount, then press until you hear a solid click. The patented puck-style push-lock design removes fiddly pins and simplifies alignment, making it ideal for quick stops, campgrounds, marinas, and busy job sites.

• No loose pins or complicated levers—one-click secure locking.
• Quick to remove with the supplied precision keys for fast hookup.
• Ships with five keys so you can keep spares in multiple locations.
• Check product images for compatible coupler styles before purchase.
