Alright, let's talk serious security with these colorful waterproof padlocks! This 12-pack gives you heavy-duty laminated steel construction with bright plastic covers in four different colors - red, yellow, green, and blue. The coolest part? Locks of the same color are keyed alike (each color comes with its own keys), but different colors can't be opened by other keys - perfect for color-coding different areas in your factory, school, hospital, or workshop. Think red for electrical boxes, yellow for tool storage, green for medical supplies, and blue for storage rooms. These aren't your average padlocks either - we're talking zinc-plated laminated steel bodies with thermoplastic shells that provide serious protection against moisture, dirt, and grime. The 4-pin cylinder and double locking mechanism make them resistant to picking and prying, while the hardened steel shackle offers maximum corrosion protection. Each lock measures 1-9/16 inches wide with a 3/10-inch diameter shackle that's 1-2/3 inches long. At 7.65 ounces each, they've got some heft to them. Perfect for storage units, garages, sheds, trailers, warehouse doors, factory gates - basically anywhere you need reliable outdoor security. Just make sure that bottom hole is covered when using outside, and always double-check the size works for your application. This pack includes 12 padlocks and 24 steel keys, giving you everything needed for organized, color-coded security system.
