    2. Gate lock

      Barry Fantich (verified owner)

      The key part of the lock doesn’t feel very strong and the other side is hard to push. I hope it holds up.

    Customer Questions & Answers

    1. Q When the lock is in the unlocked position will the gate still latch? answer now
      Asked by Michael Carpenter on March 21, 2023 9:53 AM

      This product features passage mode, which will allow the gate to be latched and still unlocked at the same time. To properly utilize this feature, please refer to the user manual for the product!

    2. A

      This is mounted on brackets with Phillips head screws. Some screws are not accessible while the gate is locked making this very difficult to remove. 

    3. Q Will this work with a double gate setup? answer now
      Asked by jacob wade on October 18, 2021 6:43 PM

      We would not recommend this model for a double gate setup as the locking bar may not latch properly if the latch hooks are not on a stationary post when the gate is closing. 

    4. Q Will this work on a chain link gate? answer now
      Asked by Jeff Smith on September 8, 2021 3:05 PM

      Unfortunately, this model is not recommended for chain link fences. 

    5. A

      The key is used to toggle the latch between locked and unlocked. When in the unlocked state, a key is not required to operate the latch and exit. 

    6. Q Can this be used on wood gates? answer now
      Asked by Isaac De La Cruz on March 5, 2021 10:20 AM

      This lock can be used on wood, vinyl, or metal gates!

    7. A

      This unit does feature a key cylinder on both sides of the unit.

    8. Q Can you only pull it to open or push as well? answer now
      Asked by Mason Bakken on July 3, 2020 10:14 PM

      The locking mechanism is pull only. 

    9. A

      The maximum post thickness for this model is 5 inches. 

    10. Q What materials are used to make the locks? answer now
      Asked by Giquel on June 20, 2020 10:41 AM

      The lock is made with non-rusting: polymers, aluminum, and stainless steel.
