METOWARE Universal Trailer Coupler Lock — Fits 1-7/8", 2", 2-5/16" | One-Hand Press-to-Lock, Hardened Alloy

METOWARE's Universal Trailer Coupler Lock is a heavy-duty, all-weather coupler security device that fits 1-7/8", 2" and 2-5/16" couplers and locks in place with a one-handed press-to-lock action.

Whether you tow a boat, camper, utility trailer, or cargo carrier, protecting your trailer at rest is essential. This METOWARE coupler lock replaces fiddly multi-piece designs with an integrated sliding mechanism and armored housing that fully encloses the trailer coupler. Corrosion-resistant finishes, a silicone dust cap, and a hardened-alloy construction help keep the lock working smoothly through seasons and roadside conditions.

How does the integrated slider simplify locking and unlocking?

The built-in slider eliminates separate pins or loose parts by creating a single, guided action: pull the slider, set the coupler inside, then push the housing to secure it. This reduces setup time and risk of losing components while delivering a tight, rattle-free fit across multiple coupler sizes. The guided movement also helps align the lock quickly, even in low light or awkward positions.

• Pull-to-position slider for one-piece operation
• Engineered fit for 1-7/8", 2" and 2-5/16" couplers
• Prevents loose or missing parts common with pin-style locks
• Delivers snug, anti-rattle engagement

Can I operate the METOWARE lock quickly when loading or towing?

Yes — the lock uses a press-to-lock cylinder that lets you secure the coupler without fumbling for a key to engage the mechanism. This one-handed operation is designed for fast deployment at boat ramps, storage lots, and campsites. The mechanism still requires the key for removal, preserving theft resistance while speeding routine use.

• Press-to-lock cylinder for instant locking
• One-handed operation speeds setup and departure
• Key required to remove the device, maintaining security
• Useful when working alone or in tight spaces

Will this lock withstand attempted tampering and harsh conditions?

The body is formed from hardened alloy steel and built in a heavy-duty boxed design that fully covers the coupler, creating a robust physical barrier against prying and cutting attempts. A corrosion-resistant finish and silicone dust cap protect internal parts from salt, rain, and freeze/thaw cycles so the lock remains functional year-round. While no lock is impervious to determined attack, this model focuses on strong materials and design to deter opportunistic thefts.

• Hardened alloy-steel construction for durable protection
• Boxed housing shields coupler from prying tools
• Corrosion-resistant coating and silicone dust cap for weather protection
• Designed as a strong visual and physical deterrent
