Offset Guard Plates are used on vestibule doors with projecting door casings (for doors not flush with the frame). These plates are easily installed by drilling only 2 holes and using a pair of through bolts and nuts. The guards are made of cold rolled steel and have a satin stainless finish. The 14in (35.5cm) overall length extends 3in (7.6cm) beyond the average lock face, protecting against unauthorized, forcible entry. There are 4 sizes available. Guard plates come complete with all necessary hardware and illustrated instructions. 7/16in (11.11mm) offset 1/8inW x 14inH (46 x 356mm) Satin Stainless Finish
