    Abstract: A push pad exit device comprising a horizontal push bar actuator mechanically linked to a vertical door handle assembly, for use on the interior side of entrance doors where a means of emergency egress is desired, is presented. The operating mechanisms of the push bar actuator and vertical door handle assembly are concealed presenting a smooth uncluttered appearance. In one mode of operation, the push pad actuator may be moved inwards towards the door face causing the door to unlatch. The push pad exit device may also be equipped with a “dogging feature” which locks the push bar actuator in the unlatched position. In this mode of operation the door is unlatched and the push pad actuator may be used as a fixed door handle. The push pad exit device may also be equipped with a keyed lock on an external face of the door.

    Abstract: A push pad exit device comprising a horizontal push bar actuator mechanically linked to a vertical door handle assembly for use on the interior side of entrance doors where a means of emergency egress is desired, is presented. The operating mechanisms of the push bar actuator and vertical door handle assembly are concealed presenting a smooth uncluttered appearance. The push pad exit device further including an improved roller latch bolt. The improved roller latch bolt allows for a roller to make contact with a ramp surface of a corresponding strike plate on a sweep side of the plate and allows for the roller support to make contact with the strike plate on a latch side of the plate.

    Abstract: An improved door rail system for holding a panel, such as a glass panel, is presented. The door rail system includes a core rail and clamping rails having a wedging geometry so that when the clamping rails are actuated with respect to the core rail, clamping force is applied to the glass panel to secure the panel within the core rail. The improved door rail system accommodates panels of varying thickness, features the use of modular side covers and incorporates a door to door jamb adjustment device allowing for angular adjustments.

    Abstract: An improved base shoe for use with panel installation removal systems. The improved base shoe includes dovetail grooves for use with a safety-seal and a weather seal, wherein the safety-seal and weather seal must be installed prior to installing a glass panel. The improved base shoe features a recess for use with taper plates having a continuous projection along an upper surface. The base shoe and taper plates are configured so as to provide a prying surface between the projection on the taper plates and a wall of the base shoe.
