Take down weak security at your gates with Sumo! You can depend on the SUMO GL2DC Double Combination Surface Mount Gate Lock to protect your pool, dock or beach access after hours. Double combination means you have to enter the access code for each side of your gate. Suitable for gates at public pools or private beaches where you control who enters and exits the property. Using the keyed cylinder lockout function, staff can lock the gate with the key and render both keypads inoperable. Everything will be locked down for the night so even users with the code cannot enter. The deadlocking spring latch prevents tampering, meaning no one will be able to jimmy the lock open. Passage mode is for times such as swimming or boating competitions, community pool or dock parties, or simply operating hours, where you have a lot of people coming and going through the gate. You don’t have time to be waiting for people to enter a code for each access. This lock is excellent for gates that surround your indoor and outdoor pools, docks, private beaches, or other liability areas to keep children from harm when you aren’t around to supervise them. No welding needed as the lock housing secures to your existing gate with the included mounting kit. Weather resistant and built from zinc plated steel, it will function in any situation. The SUMO GL2 is ideal for ornamental, aluminum, vinyl, and wood gates.

Customer Questions & Answers

  1. Q Are the numbers on the keypad backlit? answer now
    Asked by Frank on October 17, 2023 3:27 PM

    Unfortunately this product does not have a backlit keypad.

  2. A

    Yes! You may set the entry code on both sides to match each other.

  3. A

    Passage mode refers to the unit not requiring a code to open the door/gate. The lock will still latch shut but will not require a code to open the door again until passage mode is disabled. 

  4. Q Does this work on a wooden gate? answer now
    Asked by Carlos on May 30, 2022 7:54 PM

    This model can be used on most gate materials such as aluminum, vinyl, and wood gates.

  5. Q Can you have 2 separate codes? One for each door handle? answer now
    Asked by Justin on May 6, 2022 5:50 PM

    You are able to set a different code on the interior and exterior unit!

  6. A

    The lock is fully weather-rated and does not need to be installed within an enclosure when used for gate applications. 

  7. Q Can this also be set for no combination needed. (Unlocked) answer now
    Asked by Brett on November 16, 2021 5:07 PM

    Yes, this lock comes with a passage feature so you can enter without the combination if set to passage. 

  8. A

    The keypad side of the lock will need to be removed from the gate to change the combination.

  9. Q How do you prevent this corroding in a beach environment? answer now
    Asked by Steven on August 15, 2021 10:41 AM

    These units ship with a marine-grade finish to resist rust and corrosion in high salt/moisture environments. If needed, you can also apply a coat of anti-corrosion spray that can be found at normal hardware or marine stores. 

  10. Q What does double combination mean? Have you have two codes? answer now
    Asked by Andrea on March 10, 2021 1:33 PM

    Double Combination means that there is a keypad on both sides of the gate. A code will be needed to both enter and exit through the door.
