A cable operated mechanical locking external disconnect enclosure for multi-point latch uses. The enclosures provide safety, in that, once the main enclosure door is closed, and the disconnect is turned on, the main enclosure is locked and only automatically unlocks when the disconnect is turned off. Thus, the door of the disconnect enclosure is locked when the disconnect or circuit breakers are turned to the on position. There is also a manual by-pass latch for each door.

An adapter and interface permits a standard mortise lock to drive top and bottom latch mechanisms of a multi-point lock system. An actuator permits in situ adjustment of the top and bottom vertical latch projections of adjusting these projections while the door is hung in the door frame. An installation tool assists in the installation of the vertical rods in a door. A connector and carrier secures the vertical rods to the actuator and permits verification of retention of the rods in a multi-point latching system. A latch dogging indicator allows for end-user adjustment between a single-point lock and a multi-point lock system when desired. These different aspects may be employed in combination or separately with other locking systems.

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.

A panic bar latch release assembly is disclosed having an inside latch release and an outside pull type handle latch. The handle latch includes a main housing having a pivotal pull handle. The inside latch release includes a first bar mount, a second bar mount, and an elongated push bar. The first bar mount has a support bracket with a floor with a first stop wall and an extended portion with a push rod guide hole extending therethrough. A body portion is coupled to the support bracket which includes a handle mount channel which is partially defined by a second stop wall. A handle mount is pivotally coupled to the body portion. An elongated push rod is positioned within a push rod channel of the door so as to extend through the push rod guide hole.

Latch mechanisms adapted to prevent unauthorized displacement of a latch bolt from an extended, locked position to a retracted, unlocked position. The latch mechanisms prevent the failure of a latch bolt of one latch mechanism to return to an extended lock position from interfering with the ability of a latch bolt of an inter-related latch mechanism from being able to return to an extended, locked position. Further embodiments provide a mounting bracket mounted to a door to allow the associated latch mechanism to be indirectly secured to the door. Additionally, the mounting bracket may have a plurality of mounting orifices that allow the mounting bracket to be used with a wide range of latch mechanisms, as well as provide adjustable attachment of the latch mechanism to the mounting bracket.

A method of fabricating a multijunction solar cell by providing a plurality of multijunction solar cells; dispensing an uncured silicone coating on the solar cells using an automated process with visual recognition, and curing the silicone coating on the solar cell.

A door exit device may include an actuator, an upper latch, and a lower latch. The actuator may be operatively coupled to the upper latch by a first drive and to the lower latch by a second drive. Each drive may include a housing which is mountable to the exterior of a door panel and a drive rod slidably supported within the housing. The housing may include a base which is mountable to the door panel and a cover attachable to the base with the drive rod located between the base and the cover. The housing may be configured to extend from the actuator to the latch to conceal the entire length of the rod between the actuator and the latch.

An exemplary noise-reducing mechanism for door hardware includes a housing, a damper, and a stop. The door hardware includes a first component and a second component, and an operational movement of the door hardware causes relative movement of the first and second components. The housing is mounted to the first component, and the damper is mounted to the housing. The stop is mounted to the second component such that the stop engages the damper during the operational movement. The damper is configured to slow the operational movement, thereby reducing noise generated by operation of the door hardware.

A door latch system comprises an interchangeable latch assembly for securing a door to a door frame. The interchangeable latch assembly comprises a head and a latch mounted to the head. The latch is moveable between latched and unlatched positions. A driven member is operatively connected to the latch, the driven member moveable to latch or unlatch the latch. The door latch system further comprises a universal actuating assembly removably couple-able to the interchangeable latch assembly. The universal actuating assembly comprises a mounting bracket and a driving member releasably coupled to the driven member. Actuation of the universal actuating assembly translates the driving member and the driven member, moving the latch to the unlatched position. A first interchangeable latch assembly may be swapped with a second interchangeable latch assembly without requiring modification of the universal actuating assembly.

An exemplary trim lock device is configured for use with a trim comprising a lift finger, and generally includes a housing, a blocking member, and a lock actuator. The blocking member includes a projection, and is rotatably mounted to the housing for rotation between a blocking position in which the projection blocks actuating movement of the lift finger and an unblocking position in which the blocking member does not block actuating movement of the lift finger. The lock actuator is operable to rotate the blocking member between the blocking position and the unblocking position.
