Lockey SUMO GL2 Heavy-Duty Passage Lever-Handle Latchbolt Lock with Key Lockout Feature

  1. This is a latchbolt lock so it auto-locks every time the gate is closed unless you put the lock into passage mode.
  2. The SumoGL2 has a unique Key Lockout feature. Once locked with the key, it will remain locked until opened with the key. Someone without a key will not be able to open the lock—even with a valid code. So your gate can be secured without changing the code.
  3. This is also a surface-mounted heavy-duty gate lock with a keypad that requires no welding. It simply bolts onto a gate that is up to 3.5" thick (up to 5" with extension kit sold separately). It has an adjustable strike and lockout bolt which can bridge a gap between the gate and fence post of 1/16" to 2".
  4. This product comes with everything you need to install it on a gate with a rectangular frame and post.
  5. It can also be installed on a chain link fence with a round frame and post if you purchase a Lockey SUMO GL2LINX Adapter for Chain Link Gates, which is sold separately.
  6. The Sumo outdoor keyless lock comes in two marine-grade finishes: Satin Chrome Marine-Grade and Lockey's new finish: Jet Black Marine-Grade, so it is ideal for use on beach fronts or places where it will be exposed to salt.
  7. This lock works on hinged gates that swing outward.
