PACLOCK’s UCS-79A is a versatile trailer lock that can be utilized on a variety of applications! Also considered to be a universal trailer lock, it can be used on boat trailers, kayak trailers, and more. The UCS-79A is machined in the U.S. from 6061 aluminum billet and then precision machined in PACLOCK’s manufacturing facility. Machining the body versus casting the body is critical because casted bodies can be easily defeated by melting the bodies with an off-the-shelf plumber’s torch. A body that was CNC machined from solid aluminum can hold up to the torch test. Don’t buy die-cast padlocks ever! 6-Pin technology (more than the industry standard 4 pins) provides over 20,000 unique key codes and makes duplicate key combinations extremely rare. Your key number is virtually unique to you. Stainless steel spool and serrated security pins make the lock pick, bump, and drill resistant. CNC machined for U.S. precision and reliability, the lock body exceeds +/-0.003” tolerances for repeatable quality.
