The top-of-the-line LokkLatch® PRO-SL offers all the popular features of the other LokkLatch® models, with the added security of a 'self-locking' function - not only when the latch closes it will lock automatically for added security.

As the latch automatically locks, a key is required to enter and exit, providing an extra dimension of security and making LokkLatch® PRO-SL the ideal choice for installation in apartments, condos, commercial and other security-conscious properties.

Designed to fit posts up to 6" (15cm) in width, installation is quick and easy - the new polymer tail means a single hole drilled through the fence post is all that's needed to install and connect both sides of this security latch system.
