Locinox LAKQU2 Surface Mounted Gate Lock High quality gate lock with aluminum housing and stainless steel mechanism. We recommend this lock as the standard for your industrial gates. The latch and dead bolt have 3/4" continuous adjustment to allow perfect latching / locking of the mechanism. A stainless steel throw of 7/8" guarantees secure locking. Handle depends on color: silver locks ship standard with the modern aluminum anodized handle pair and all other colors ship with the black ornamental handle pair. The latch gap required is keep dependent, but the standard and security keeps require a 1-1/4" latch gap. For a fast and highly precise installation, we recommend using the Drill-Fix drilling jig.Specs ISO 9227 KTL / E-coated lock box withstands 1000 hours of salt spray test Easy left or right changing of the self-latching daybolt Throw of the dead bolt, 7/8" in 1 turn of the key Key-operated self-latching bolt 4-hole mounting with two hex head socket screws Center distance bolts: 2-3/8" Continuous adjustment of the deadbolt up to 3/4" without removing the lock box Stainless steel mechanism
