Kohree Trailer Coupler Lock for 2" and 2-5/16" Couplers — Heavy-Duty, Weather-Resistant Snap-On Anti-Theft

The Kohree Trailer Coupler Lock is a heavy-duty, weather-resistant hitch lock that fits standard 2" and 2-5/16" trailer couplers to help prevent unauthorized towing.

Designed for RVs, boat trailers, utility trailers and fleet equipment, this coupler lock combines a rugged steel shell with a bright high-visibility finish and a tool-free snap-on design. It secures over the hitch connection to discourage theft and accidental hookup while offering corrosion-resistant features for year-round outdoor use. The kit includes multiple keys, rubber dust covers, and a storage box so you can deploy and store the lock with ease.

How does the Kohree coupler lock stop theft without tools?

The lock uses a thick, reinforced steel body that resists common break-in methods such as prying and hammering. Its wrap-around design covers the coupler and prevents the ball from seating, so a thief cannot hitch up a trailer even if they can access the coupler itself.

• Heavy-gauge steel shell for pry and impact resistance
• Encloses coupler to block ball engagement
• Bright orange finish deters opportunistic thieves via visibility
• Snap-and-lock mechanism locks securely without tools

Will this fit my trailer’s coupler size?

This Kohree model fits the two most common coupler sizes: 2" and 2-5/16" ball couplers. It’s intended for standard-style hitch heads; confirm your coupler type and dimensions before purchasing to ensure a snug, secure fit.

How does the lock perform in bad weather?
