Magnum Padlocks

Magnum brand padlocks are manufactured by the Master Lock Company. Master Lock created the Magnum series of padlocks to offer the strength and lower price of laminated steel padlocks, but with enhanced features to improve security, durability, and weather resistance. The Magnum Laminated padlocks are an excellent choice for all-weather applications where higher security is required. There are a number of upgrades from the traditionally laminated steel padlocks featured in the Magnum Padlocks. The most obvious difference can be seen in the padlock body cover. The Magnum padlocks have a stainless-steel body cover and stainless-steel top and bottom body caps.

This stainless-steel jacket protects the laminated steel body from the elements. The improved security and resistance to cutting come from the octagonal boron-carbide steel shackle. The octagonal shape of the shackle is much more difficult for cutting tools to grab and boron-carbide is 50% harder than regular hardened steel. These two features improve the strength of the shackle. The final feature that improves security is the shackle’s dual locking ball bearings instead of dual levers. Shackles locked with internal ball bearings provide maximum resistance against prying and hammering. offers a variety of Magnum padlocks online for sale.
