The LokkLatch® PRO-SL is a commercial grade self-locking security gate latch. Not only can this lock be operated and locked from either side of a gate, when the latch closes it will lock automatically for added security. As the latch automatically locks, a key is required to enter or exit, providing an extra dimension of security and making LokkLatch PRO-SL the ideal choice for installation in apartments, gated communities, commercial and other security-conscious properties.

The LokkLatch PRO-SL with strong, moulded polymer construction and stainless steel components gives you the benefits of key-lockability and reliable latching action with superior design and rust-proof components. 

LokkLatch PRO-SL can be installed onto posts ranging from 38mm to 150mm, making it perhaps the most versatile gate latch ever manufactured.  It fits to both right and left-hinged gates.

There are two models available: LLP1S-L designed for use on metal posts, and LLP2S-L which features deeper side fixing legs for added strength.

There are keyed-alike models as well as keyed-different models.
