The Bump Stops Here!
Lock bumping — an easy and undetectable lock picking technique, uses a specially–crafted bump key to open a pin tumbler lock. As a world leader in security hardware, Master Lock Company stepped forward to create a revolutionary new lock cylinder that provides unsurpassed protection against lock bumping, exceeding the highest, Grade 6 criteria for bump resistance established in ASTM Standard F883-09.
BumpStop® employs an innovative, patent pending design which prevents the transfer of force from the bump key to the pins — so the lock stays locked.
This technology is available in a broad array of American Lock® and Master Lock® Commercial Grade Padlocks today.
BumpStop® Advanced Cylinder Technology is available in a broad range of Master Lock® NightWatch™ deadbolts and combination deadbolts as well as a variety of Commercial Grade 2 and Residential Grade 3 Door Hardware to provide maximum protection against bumping for all security hardware applications.
