Master Lock Keyed Alike Locks with BumpStop Technology

Introducing BumpStop TECHNOLOGY - Lock bumping, a surprisingly simple method of breaking into locked doors and padlocks, is undoubtedly the newest emerging threat to personal property security. Virtually all locks currently in use are particularly vulnerable to bumping, but not anymore. Our BumpStop Advanced Cylinder Technology features an innovative design with a unique reverse rake tapered driver pin, high-performance springs, and tightly machined cylinder chambers. This design prevents the transfer of force from the bump key to the pins during a bump attempt, effectively blocking rotation of the cylinder to keep the lock secure.

This listing is for TEN (10) padlocks keyed alike, meaning the same key unlocks all ten locks. You will also receive twenty keys in total. These padlocks are equipped with the BumpStop Advanced Cylinder Technology for enhanced security. If you prefer a similar lock without this technology, simply search for 3KALF in our storefront.

Ideal for outdoor applications requiring multiple locks that can be opened with a single key, these padlocks feature a 1-9/16in (41mm) wide reinforced laminated steel body with a black bumper. The shackle is 1-1/2in (38mm) tall and 9/32in (7mm) in diameter, providing excellent security with dual ball bearings for maximum pry resistance. The 4-pin tumbler cylinder adds an extra layer of security, while the hardened steel bottom plates offer resistance against drilling. Top and bottom bumpers also help prevent scratches.

Backed by a limited lifetime warranty from a trusted name, these padlocks are designed to provide the highest level of security for your peace of mind. Need them quickly? Inquire today and we can typically have them shipped to you within a couple of days.
