PACLOCK 81A Trailer Door Lock

What is UCS?

PACLOCK's Universal Cylinder System (UCS) is a cylinder option that makes it easy for you to key different padlock styles alike to give you full customization of your lock setup. With UCS, you can expand your system to an unlimited number of locks with only one key, or even start your own master or grand master lock system. All brass, aluminum and stainless steel components render all UCS padlocks rustproof. 6-Pin technology (when most locks only have 4 pins) provides over 20,000 unique key codes and makes duplicate key combinations uncommon, meaning your key number is virtually unique to you.

Stainless steel spool and serrated security pins make the lock pick, bump and drill resistant. Dual ball bearing locking and other security features make the lock bypass and shim proof. Change to a long length shackle in seconds using PACLOCKs modular UCS shackles. CNC machined for U.S. precision and reliability, both the cylinder and lock body exceeds plus or minus 0.003 tolerances for repeatable quality.
