Kohree Trailer Lock for 2" & 2-5/16" Couplers — Forged Steel, Weatherproof Handle

The Kohree Trailer Lock is a heavy-duty, adjustable coupler lock that fits both 2" and 2-5/16" trailer balls and provides quick, weatherproof anti-theft protection with an easy top handle.

If you store or tow a trailer, securing the coupler is one of the simplest ways to prevent unauthorized hooking and theft. This Kohree lock is forged from hardened steel, designed to resist cutting and prying, and works with the two most common coupler sizes so you don't need multiple locks. It combines a user-friendly top handle, four included keys, and weather seals to keep the locking cylinder operating in rain, dust, and mud.

How does this lock fit different trailer coupler sizes?

The Kohree Trailer Lock is engineered to accommodate both standard 2" and larger 2-5/16" ball couplers without extra adapters. Its adjustable internal shape and robust shank align with the most common coupler openings for a snug fit. Before buying, verify your coupler style and dimensions to guarantee compatibility.

• Designed for 2" and 2-5/16" ball couplers
• Tool-free adjustment for quick installation
• Works on many travel trailers, utility trailers, and boat trailers

What makes the lock abrasion and weather resistant?

Corrosion and forced entry are common attackers of trailer security hardware. Kohree builds this lock from forged, hardened steel and finishes it with a matte black coating that resists rust and reduces glare. Rubber dust plugs cover the keyways to keep debris and moisture out, helping the cylinder function reliably over time.

• Forged, hardened steel resists sawing, prying, and hammering
• Matte black non-reflective coating reduces corrosion and visibility
• Four rubber protective plugs block rain, mud, and dust

Is the lock easy to use during frequent hookups?

Yes — the top-mounted handle simplifies carrying and positioning the lock on the coupler, so you can secure or remove it quickly without awkward maneuvers. The lock ships with four keys so multiple users can access the trailer without sharing a single key. Its straightforward operation suits both occasional users and those who tow regularly.

• Ergonomic top handle for fast placement and removal
• Includes four keys for multiple users or backups
• Quick lock action saves time at campsites or storage lots

The product is promoted as part of a broader Kohree security system, meaning accessories and guidance are available if you want to expand protection for your trailer.
