Customer Experiences
"75 mph winds during a storm knocked down a HUGE pine tree in my back yard - directly on my shed. Miraculously my 1986 Harley inside was fine. I was so proud to see my Master Lock still holding tight in the hasp with the entire shed collapsed. These are the only locks I would ever use."— john @ Levittown, NY Full Story
"One of our No. 176 locks received at least two rounds from a shotgun. We figure one round with Double 00 buck and another with bird shot. After two darn near point blank shots the lock is no longer usable via the combination or the key override. But your lock held tight!! I never thought that our locks would be put under such stress."— Michael @ Missoula, MT Full Story
