It is recommended to edge mount the EPT/EPTL in the upper half of a steel door and the lower half of a wood door. The EPT/EPTL Lead Cover should be a minimum of 6” [152,4mm] from the middle butt hinge cutout or centered between the butt hinges. Prior to installation, ensure that you have the correct version of the EPT/EPTL for the door/frame. The EPT is used for door swing gap distances of 2-1/2” [63,5mm] or less between door edge and the door frame. The EPTL is used for longer door swing gap distances greater than 2-1/2” [63,5mm].

A simple measurement may be taken to determine the correct EPT/EPTL for the application. To measure the swing gap distance, open the door its full travel distance. Measure the distance from the centerline of the door edge to the centerline position on the door frame as shown in Figure 1. If this distance is 2.5” [63,5mm] or less an EPT may be used. If the distance is greater than 2.5” [63,5mm] an EPTL must be used. Once the correct unit is determined, use the following step by step procedure to correctly install the EPT/EPTL.
