Medeco 54 System All Weather Padlock

The Medeco 54 System All Weather Padlock is a high-security padlock designed for indoor and outdoor use. It features a 5/16" x 2-3/8" shackle made from baron alloy steel for cut and pull resistance. The cylinder uses a 00 Original High Security keyway with hardened stainless steel inserts. UL437 listed, it provides triple locking action for pick resistance.

Installation and common issues

The padlock installs by simply engaging the shackle through a hasp or chain link. Its weather-resistant body cover protects the cylinder mechanism from moisture and debris. The primary issue arises if the key is lost, as the patented keyway prevents unauthorized duplication. Ensure the shackle diameter matches the attachment point before purchase.

Ideal uses and limitations

This padlock suits users needing UL437 listed security for gates, storage units, or commercial doors exposed to the elements. The Keyed Different configuration ensures unique access per lock. It is not for buyers needing multiple locks operated by a single key. It also does not suit applications requiring a shrouded or hidden shackle design.

What comes in the box with the Medeco 54-51F00-00 and what must I buy separately?

The box contains the padlock with its standard black body cover, satin brass cylinder, and baron alloy steel shackle; additional keys or a master-key system are sold separately.

Which version of the Medeco 54 System All Weather Padlock should I choose for UL437 high-security needs?
