The HPC VDG10 Anti-Thrust Lock Guard Plate is HPC's strongest and most popular guard plate. The plate is 14 inch (35.5cm) long and made from 2 pieces of 16 gauge cold rolled steel, welded together with a baked matte bronze finish. This guard plate offers maximum resistance to prying and forcing. The VDG10 mounts onto your door with 2 carriage bolts going through the door, and is anchored with a nut and cap nut on the inside. Four wood screws go into the edge of the door. Guard plates come complete with all necessary hardware and illustrated instructions.
