Kohree Heavy Duty Trailer Coupler Lock, Trailer Tongue Lock Hitch Locks RV Trailer Locks fit 2-5/16 Inch, 2", 1-7/8" Couplers, Durable Structural Steel Safety Tow Lock, 4 Keys & 4 Dust Covers, Black

The Kohree Heavy Duty Trailer Coupler Lock / RV Trailer Lock [that] fits 2-5/16" Inches, 2" Inch and 1-7/8" Inch Couplers / Sturdy Structural Steel / Safety Tow Lock with 4 Keys & 4 Dust Covers (Black) is one heavy-duty piece of metal. The weight of the product alone denotes "Heavy-Duty." Claimed to weigh-in at just shy of EIGHT(8)Lbs., I have no doubt it will deter the most determined of thieves. Nice that the keyed locking mechanism has a "push-to-lock" capability, after being opened with the key. Also like that it fits most of the three sizes of trailer hitch-couplers. Claimed to withstand sledgehammers, power tools, bolt cutters or crowbars - what's not to like.

We got the Kohree Heavy Duty Trailer Coupler Lock to try. It is probably the heaviest well built trailer hitch lock we’ve ever owned. It came with 4 keys and 4 dust covers for the lock. We liked the high-strength structural steel casing of the lock, the ease of installing it, and it is sure to deter theft.
