  • Patent number: 7628430
    Abstract: An adjustable square metal tubular strut, comprised of two square metal components, that when telescoped together and positioned horizontally at the center hinge pins on most width double entrance in-swinging doors, stops the deflection of said doors in wind load situations. The preferred embodiment of the strut is comprised of a plurality of predetermined holes for fastening the strut components together in any width configuration, and metal ā€œUā€ shape straps attached to both ends of the strut with holes to receive the hinge pins, ultimately fixing the strut in place. Located along the face of the strut are a series of threaded holes of predetermined size and location, that where applicable, will receive two threaded torque screws, with a torque lever arm on the front end and a pressure foot on the inner end, that when tightened will firm the strut to the doors.
