Customer Questions & Answers

  1. Q Can the raised walls be cut away? answer now
    Asked by Bernetta A Fleishell on February 7, 2020 4:15 PM
    Answered by the admin

    This would be entirely based on your discretion. Please bear in mind that doing so will void the lock warranty and the lock will not be eligible for a return/exchange.

  2. Answered by the admin

    There should not be an issue in this application as this deadbolt was designed for exterior/construction environments. 

  3. Q Can this be cut off with bolt cutters or any tool? answer now
    Asked by Debra on January 7, 2020 6:01 PM
    Answered by the admin

    The raised walls of this unit make the shackle very difficult to reach with bolt cutters and other tools. However, this may also depend on the application in which it is installed.

  4. Q Could this be used on a gym locker? answer now
    Asked by AP on November 4, 2019 12:35 PM
    Answered by the admin

    This lock can certainly be used on locker doors as long as they have the correct mounts for a standard padlock. 

  5. Answered by the admin

    This model is a mechanical, single combination padlock. Only one code may be set at a time. If you are looking for a lock that can hold multiple entry codes, you will want to take a look into the electronic lock series.

    It should have no issue working in harsh weather. 

  7. Q How many locks come in an order answer now
    Asked by Jeniffer Villatoro on July 15, 2018 2:55 AM

    There is only a single padlock for the price on the website but you can order as many as you need. The picture is only designed to show you how it looks and operates.
