Solid Brass Rectangular Padlocks

These solid brass padlocks perform in even the harshest outdoor or corrosive environments. Hardened boron alloy shackles offer superior cut resistance, while dual stainless steel ball bearing locking mechanism resists pulling and prying. Rekeyable five- or six-pin brass cylinders and serrated pins are pick resistant with tens of thousands of key changes.

Shackles are chrome plated for corrosion resistance; rust-resistant brass shackles are available as an optional upgrade for harsh outdoor environments.

Weatherbuilt™ Padlock Protection is available for the 2" and 1-3/4" model, with the added optional upgrade of stainless steel shackles for the best combination of corrosion- and cut-resistance.

Enhanced keying option includes BumpStop® Advanced Cylinder Technology and Edge® Key Control.
