SUMO® GL2 Surface Mount Gate Lock

About the SUMO® GL2

You can depend on the SUMO® GL2 Surface Mount Gate Lock to protect your pool, dock or beach access after hours and whenever you need it. Using the keyed cylinder lockout function, staff can lock the gate with the key and render the keypad inoperable. The lock will be secure so even users with the code cannot enter. The deadlocking spring latch prevents tampering, meaning no one will be able to force the lock open. This gate lock also features a passage mode, which allows the gate to be opened freely without a passcode from both sides during hours of operation. This lock is excellent for gates that surround your indoor and outdoor pools, private beaches, or other liability areas to keep children from harm. No welding is needed for installation as the lock housing secures to your existing gate with the included mounting kit. Weather-resistant and built from zinc-plated steel, this lock will function in any situation where reliable security is needed. The SUMO GL2 is ideal for ornamental, aluminum, vinyl, and wood gates. The SUMO® GL2 also installs on chain link gates with the SUMO GL2LINX Adapter, sold separately.
