Stainless steel padlocks

April 1, 2011
These stainless steel padlocks are built to withstand extreme weather and the harshest conditions. They feature ASTM grade 6 status and corrosion-resistant construction. The locks are available in 1 3/4-inch and 2-inch padlock widths, with a choice of 1 1/8-inch or 2-inch shackle heights, with replaceable five- and six-pin cylinders that provide a large number of key changes.
