Master Lock M115XQLF Covered Padlocks – 4-Pack, Keyed Alike, Heavy-Duty Weather Resistant

Built for outdoor security you can rely on

The Master Lock Magnum M115XQLF covered padlocks blend a tough laminated steel body with weather-ready components, delivering durability where it matters most. With a 1-7/8 in. (48 mm) wide lock body framed by stainless steel and zinc outer parts, these locks stand up to the elements. Rust-Oleum Certified protection provides a lifetime guarantee against rusting on the lock body, while covered keyways and shackle seals offer extra weather protection for everyday outdoor use.

The 5/16 in. (8 mm) diameter octagonal boron-carbide shackle is 1-1/2 in. (38 mm) long and is 50% harder than hardened steel, delivering strong resistance to cutting and sawing. A 4-pin cylinder minimizes picking, and dual locking ball bearings enhance resistance to prying and hammering. All of these features are backed by a Lifetime Guarantee, giving you peace of mind for long-term security in outdoor settings.
