Adjustable fastening device for securing a sensing edge to any of a plurality of doors

An adjustable fastening device for securing a sensing edge to an edge of a door, said fastening device comprising:

• a mounting plate for being attached to a door edge and having first and second lateral ends, said mounting plate including a first surface for being in facing relationship with the door edge and a second surface for being in facing relationship with a sensing edge;
• a first elongated member extending from said mounting plate proximate said first end thereof;
• a second elongated member extending from said mounting plate proximate said second end thereof and being detachable from said mounting plate, said first elongated member being spaced apart from said second elongated member a first predetermined distance for receiving an edge of a first door having a thickness which corresponds to the first predetermined distance between the first and second elongated members;
• and
• a third elongated member extending from said mounting plate proximate said second end thereof between said first and second elongated members and being detachable from said mounting plate, said first elongated member being spaced from said third elongated member a second predetermined distance for receiving an edge of a second door having a thickness which corresponds to the second predetermined distance between the first and third elongated members, where an installer can selectively detach one of said second and third elongated members from said mounting plate such that the first elongated member and the other of the second and third elongated members are spaced a selected distance for receiving an edge of a door having a thickness which corresponds to the selected distance, and where the adjustable fastening device is adaptable to receive one of a plurality of different thickness door edges.
