Master Lock Magnum Heavy Duty Solid Steel Padlock with Boron-Carbide Shackle – Outdoor Gate & Shed Lock, 2-1/2 in Wide

Overview

The Master Lock Magnum M930XKADLH padlock blends a 2-1/2-inch-wide solid steel body with a weather-ready design built to endure outdoor environments. The 7/16-inch diameter octagonal boron-carbide shackle (Tough-Cut) measures 2 inches in length and is 50% harder than standard hardened steel, delivering strong resistance to cutting and sawing. Complemented by a 5-pin cylinder and dual locking ball bearings, this lock emphasizes security while maintaining smooth, reliable operation.

Engineered for outdoor and high-traffic storage areas, it stands up to rain, dust, and rough handling. The covered keyway helps keep moisture out, and a reinforced body bumper guards against scratches that can occur when gates swing or sheds are moved around. The inclusion of two keys adds convenience for trusted users, and the Lifetime Guarantee provides lasting peace of mind from a brand you know and trust.
