The aluminum security keep is used as a standard for industrial and chain link gates as well as any gate where higher security is desired. The patented stainless steel anchoring system prevents prying the gates open and eliminates the need to install a transom over the gate. The unique Quick-Fix bolt ensures a fast and strong installation. The adjustable stop plate with rubber bumper adjusts to gate profiles up to 2-1/2" and fits on all latch posts 1-1/2" or larger. Latch gap: 1-1/4"
