Customer Experiences

"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."
