Exit device mount with closed termination

A method for installing an exit device on a door comprising:

• providing a door having a substantially planar surface for mounting an exit device, the surface having a first end near a hinge and a second end opposite the hinge;
• providing an exit device including an elongated rail having opposite first and second ends and a rear portion with a first opening adjacent the first rail end and a second opening adjacent the second rail end for attachment to the door surface, the first rail end further having a front portion that inhibits access to the first rail opening in a direction normal to the rail rear portion;
• providing a mount having a cantilevered portion extending therefrom;
• providing a door marker jig having a first alignment opening for marking a location on the door for the mount and a second alignment opening for marking a location on the door for the second opening;
• placing the jig on the door at a desired location so that the first alignment opening is adjacent the door surface first end and the second alignment opening is adjacent the door surface second end;
• securing the jig to the door surface at the desired location;
• marking the door surface through the first and second jig alignment openings;
• removing the jig;
• securing the mount to the door surface at the mark for the mount such that the mount cantilevered portion provides a space between the cantilevered portion and the door;
• securing a fastener to the door surface at the mark for the second opening;
• placing the entire rail rear portion in contact with and flush against the door surface such that the mount extends through the first rail opening;
• sliding the rail along the plane of and in contact with the door surface to engage the rail rear portion adjacent the first rail opening between the mount cantilevered portion and the door;
• and
• securing the second rail end to the door surface second end from movement along the plane of the door and preventing the first rail opening from disengaging from the mount.
