Take down weak security at your gates with Sumo! You can depend on the SUMO GL2 Surface Mount Gate Lock to protect your pool, dock or beach access after hours. Using the keyed cylinder lockout function, staff can lock the gate with the key and render the keypad 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, 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.

  1. Home gate security


    Ordered this latch without really knowing if it was right for the job. Turns out that it was really sturdy and exactly what we needed for additional security on a busy street. The lock/latch system is so adjustable that it would fit just about any gate.

    Robert Austin (verified owner)

    The directions were easy to follow. Took some effort, but is well worth it.
    One problem, one call to technical support, and problem resolved.
    I will buy more of these locks for our other pool gates.

Customer Questions & Answers

  1. Answered by the admin

    You would be correct! Each button is pushed independently until the full code is complete. Once the valid code has been entered, pulling down on the handle will retract the latch.

  2. Answered by the admin

    The maximum thickness that this lock will support is 3 1/2 in.

  3. Answered by the admin

    You would have the ability to install the lock in this manner. However, the noncoded side acts as a passage handle and will unlock the latch when turned.

  4. Answered by the admin

    A closing bar is also known as a gate closer. This is a device that prevents your gate from slamming shut after entry. You may use any gate closer you wish for your application. 

  5. Answered by the admin

    This model is normally locked but it can be set into a passage mode where no code is required for entry until it is disabled.

  6. Q Can this be installed on a wood fence gate? answer now

    Yes, this lock can certainly be used on a wooden gate.

  7. Answered by the admin

    This is a mechanical lock with no electronics. Because of this, there is no option for scheduling with this model.

  8. Q Can this mechanism be installed on a chain link gate? answer now

    Answered by the admin

    These units typically will not mount to rounded posts such as those used for chain link fencing. However, if you are able to weld a gate box to the gate for installation, the SUMO should work great!
