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.

  4. Works as advertised

    Andre Williams (verified owner)

    Works well, but was a bit tedious to install. Lots of pieces to put together. Had 2 handymen turn down the install once looking at the instructions and all the pieces.

Customer Questions & Answers

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

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

  2. Answered by the admin

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

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

    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. 

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

    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.  

  5. Q Is there a kit to fit this on a round frame chain-link gate? answer now
    Asked by Ray Glidewell on February 23, 2021 11:03 AM
    Answered by the admin

    There certainly is!

  6. Answered by the admin

    The combination does not need to be entered in a specific order, but if a number that is not part of the combination is depressed, the lock will not unlock even if the correct numbers were also input. All numbers in the combination must be depressed and all other numbers must be clear in order for the door to unlock. 

  7. Q Would this work on an inward opening gate? answer now
    Asked by Ira Ungerleider on January 25, 2021 4:21 PM
    Answered by the admin

    Since this lock is double-sided, the handing could be reversed so that the bolt is on the interior side of the gate and you would still have coded access through both sides. 

  8. Q Can this be used on a vinyl gate? answer now
    Asked by david ellinger on October 19, 2020 3:06 PM
    Answered by the admin

    This lock is great for use on Vinyl, Wood, or Aluminum gates.

  9. Answered by the admin

    As this is a mechanical lock and not an electronic model, you can only have one active access code at a time. To have the ability to enroll individual access codes, please feel free to check into any of our Electronic styles. For more information, you are welcome to dial into our sales line at 937-247-9327, option 1!

  10. Q Says it doesn't need to be welded, but can it be welded? answer now
    Asked by Ian on October 8, 2019 6:08 PM
    Answered by the admin

    It can be welded into place if desired.
