A dock door assembly and a dock door assembly kit are provided for use in a dock door opening for installation in a warehouse. The dock door assembly comprises a pair of vertical tracks, with each vertical track configured to be attached to a wall along opposing lateral sides of the dock door opening. The dock door assembly also comprises a multiple, horizontal section door characterized by a vertical height when closed and mounted on the pair of vertical tracks. The dock door assembly further comprises a spring shaft assembly and a pair of headplates with each headplate having a U-shaped opening to receive each end of a torsion shaft. Further, the dock door assembly may comprise a pair of door cables and a pair of corner cable attachments connecting each door cable to the spring shaft assembly.

An improvement for use with a door latch assembly for a roll-up door includes a shim dimensioned and shaped to be positioned over a latch cover of the latch door assembly and to be slidingly moved to a shim extended position wherein a shim tang extends beyond a latch slide tang of the latch assembly. The shim is configured so that, if the latch assembly is mounted to a rolling door and is locked into an unsecured position by a first lock, wherein the slide tang does not engage the door jamb, the shim can be moved to and locked in the shim extended position to secure the rolling door without removing the first lock.

The present lift lock includes a slide having feet and a slot between the feet, where such slide further includes an interior generally full length wall for acting as a stop, and where such slide further includes gripping ribs that increase in width from the front end of the slide to the rear end of the slide.

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.

A latch assembly for a tonneau cover. The latch assembly includes a button and a slider. The slider is movably coupled to the button. Movement of the button in a first direction causes the slider to move in an unlatching direction. Movement of the button in a second direction causes the slider to move in a latching direction.

A security device for a door in a doorway. The device includes a floor-carriable portion and a door-carriable portion magnetically co-operable with the floor-carriable portion to stop the door opening past a communication position at which the door is positioned to guard the doorway and ajar to enable the communication via the doorway. At least one of the floor-carriable portion and the door-carriable portion is reconfigurable to allow the door to open past the communication position.

A magnetic latch for fastening a closure member to a support. The magnetic latch comprises a latch bolt assembly comprising: a first elongated housing configured to be mounted with its rear side facing either the closure member or the support; a second housing connected to and positioned underneath the first housing, the second housing being rotatable with respect to the first housing around the vertical direction between a first rotational position in which the latch bolt assembly is operable for a right-handed closure member and a second rotational position in which the latch bolt assembly is operable for a left-handed closure member; and a latch bolt mounted in the second housing. The different rotational positions of the second housing allow using a horizontally moveable latch bolt while retaining a symmetrical placement on the closure system irrespective of the handedness of the closure member.
