    摘要: The inclusion of a galvanneal material with a door protection plate and methods of manufacturing thereof are disclosed. In some embodiments, a door protection plate may include a substrate, a plurality of holes, a first coating of zirconium polymer, and a second powder coating. Incorporating a galvanneal material as a first coating provides a conductive surface for adhesion of the powder coating, and additional corrosion prevention for the door protection plate.

    摘要: An assist apparatus utilized within a door system to aid in opening the door. The assist apparatus may include one or more door activation devices (e.g., a first door activation device and a second door activation device, such as pulls on opposite sides of a sliding door) that can rotate around a pivot location. Moreover, the assist apparatus may further include one or more assist components operatively coupled to the one or more door activation devices. The door activation device(s) are configured to be operatively coupled to a sliding door and allow for rotation of at least a portion of the door activation device. The assist component(s) of the door activation device(s) aid in opening or closing the sliding door by engaging a door frame, wall, or the like as the door activation device is rotated.

    摘要: A pull handle may include a chassis, a latch disposed at least partially in the chassis, a thumb turn, and a dogging fastener movably disposed on the thumb turn. The thumb turn may be rotatable between a locking position and an unlocking position, where the thumb turn is coupled to the latch such that when the thumb turn is in the locking position the latch is in an extended position and when the thumb turn is in the unlocking position the latch is in a retracted position. The dogging fastener may be configured to move between a dogging position and an undogging position, where in the dogging position the dogging fastener engages the chassis to inhibit rotation of the thumb turn.
