This model combines the Lokk Latch Series 2 model along with the External Access Kit. The External Access Kit is a lockable push button accessory which operates by way of a connecting rod (adjusts 1"-6" posts) between the latch and kit, that allows gates to be operated from outside the fence. Lokk Latch is an ideal latch for general purpose gates around the home. Construction of quality moulded polymers & stainless steel ensures no rusting, binding or staining. Lokk Latch takes a radical new approach to the gravity latch principle and combines the unique benefits of key lockability and reliable latching action with superior rust free components.
