Master Lock Keyed Laminated Padlocks, Blue Weatherproof Covers, 3-pack, 1-1/2 In.

Master Lock's 312TRI Keyed Padlock 3-Pack delivers reliable security for outdoor storage, gates, sheds, and equipment protection. Each lock features a laminated steel body encased in a weather-resistant thermoplastic cover that shields against rain, snow, and UV exposure. The case-hardened steel shackle resists cutting and tampering, while the cylinder and dual locking steel levers provide pick and pry resistance. All three locks are keyed alike, allowing a single key to open every unit—a convenience that simplifies key management for homeowners, facility managers, and contractors managing multiple entry points.

Built to endure harsh climates and demanding outdoor environments, these padlocks combine durability with practical design. A quick snap cap on the bottom helps minimize key cylinder jams caused by dust, dirt, and freezing. Three keys are included with the set, and the vivid blue finish provides high visibility for quick identification while adding a professional appearance to any secured area.
