  1. Solid, basic spin dial lock

    Posted by Kit on 25th Sep 2019

    When in doubt, this is the lock to choose for your safe or vault. It is sturdy, well made, easy to install and easy to use. All the holes lined up with those in my vault door but the screws provided were the wrong size. I just used the screws from the lock I had removed.

  2. Great price, solid parts

    Really needed just the lock but it was less expensive to buy the whole kit. It was basically just a swap over because the lock I had was temperamental and would stick every once in a while. The instructions that came with the kit were great except for when it came time to change the combination. Had to go to the manufacturer website to get an updated instruction sheet. But I will buy again when the need arises without hesitation.

  3. I’m happy
