Brady's purple aluminum, keyed-different padlock offers a 3" shackle. The anodized aluminum finish on the body provides better fade resistance outdoors and a better corrosion resistance in comparison to a standard steel shackle. This padlock, with one per package, is lightweight yet rugged and features an FDA-approved lubricant in the cylinder and key retaining safety feature. With options available for custom keying, this padlock is also available in, additional package sizes and eight colors, including black, green, blue, silver, red, orange, yellow and brown.
