Master Lock Padlocks & Cable Locks

Master Lock: A Century of Padlock and Cable Lock Excellence

Master Lock has been synonymous with dependable security since 1921, when founder Harry Soref revolutionized the industry with a breakthrough laminated padlock design. Inspired by the layered steel construction of bank vaults and battleships, Soref's design bridged the gap between cheap, easily defeated locks and expensive, heavy alternatives — producing strong, reliable, affordable padlocks. More than a century later, that same engineering philosophy drives every padlock and cable lock in the Master Lock lineup.

What Sets Master Lock Padlocks Apart

Browse the full range of Padlocks & Cable Locks and you'll quickly see the breadth of Master Lock's offering. Padlocks come in an extensive range of body types, sizes, shackle lengths, and widths, with keyed, combination, and dial locking options.

• Laminated Steel Padlocks — Laminated padlocks stack steel plates together rather than using solid bodies, and this layered design resists corrosion while providing good strength at moderate cost, making these locks popular for outdoor applications. Classic models like the No. 3 and No. 5 series are enduring workhorses for garages, trailers, and storage units.
• Pro Series Shrouded Shackle Padlocks — Shrouded shackle padlocks protect the shackle inside additional housing, leaving only a small portion exposed and making it extremely difficult to attack with cutting tools. The 6321D Pro Series is a standout choice for high-value tool trailers and equipment storage.
• All-Weather Combination Padlocks — Models like the 1174 and 1175 series feature brass or stainless steel bodies engineered for maximum corrosion resistance, ideal for outdoor and marine environments.

Master Lock Cable Locks: Flexible Security for Every Application

Master Lock offers U-locks, cable bike locks, folding bike locks, Python locks, looped-end cables, and more — a range capable of protecting bikes, motorcycles, scooters, kayaks, and lawn equipment in a variety of settings and circumstances.

• Python™ Adjustable Locking Cables — Python adjustable cable locks cinch down and bring the cable tight around the object being secured, making it harder to cut. The 8413KA Python features braided steel construction with a protective vinyl coating that resists scratches.
• Integrated Cable Locks — Models like the 8114D offer a set-your-own combination mechanism paired with braided steel cable, eliminating the need to carry a separate padlock.
• Keyed-Alike Options — Master Lock offers keyed-alike cable lock and Python lock options so you can use one key across multiple locks — a major convenience for fleet operators, contractors, or families who ride together.

Built-In Resistance to Real-World Attacks

Master Lock's integrated padlock designs feature a laminated steel body for maximum strength and reliability, with a 4-pin cylinder to prevent picking and dual locking levers that provide resistance against prying and hammering. Chain and cable locks are designed with hardened steel links or braided steel cables to resist cutting and sawing, and when paired with a strong lock to prevent prying or pulling attacks, they are a reliable security solution for low-to-medium risk areas.

Whether you're securing a gate, a trailer hitch, a bicycle, or outdoor power equipment, Master Lock's padlocks and cable locks deliver over a century of trusted engineering in every application.
