A security lock hardware box is provided for installation in a door sash. The lock hardware box is installed in a door sash for receiving locking hardware. It has a body part having first chamber for receiving a door latching mechanism, and a second chamber for receiving a door locking mechanism. Front and rear cover plates securable over the front and rear face of the body part with respective openings and holes to receive the locking and latching mechanisms. The body part has protrusions for fitting within the door sash, the length of which can be greater to provide greater strength and security regardless of the size of the lock hardware box or the size of the door sash that can accommodate the lockbox.

A security sliding barrier with a sliding panel, a fixed panel, a latch channel, a lock, a strike plate, and an interlock assembly. The sliding panel is positioned between the latch channel and the fixed panel. The latch channel mounts to the frame distal to the fixed panel and the lock is mounted on the sliding panel and extends toward the latch channel. The strike plate is attached to the latch channel and has a receiver aligned with the lock that receives the lock when the security sliding barrier moves to a closed position, locking the first side of the sliding panel to the latch channel. The interlock assembly has a fixed interlock on the fixed panel and a sliding interlock on the sliding panel that engage when the security sliding barrier is in the closed position, locking the second side of the sliding panel to the fixed panel.

An infill adaptor for mounting a screen between upper and lower rails of a balustrade. The upper and lower rails have respective channels which open toward each other. The infill adaptor has a generally L-shaped body with a rail engaging leg extending generally perpendicular to a sash engaging leg.

A door which is adjustable in length and breadth is defined by an outer sash having a generally rectangular configuration. A hinge side of the sash nests within a U-sweep member running along its length. The U-sweep member interfaces with the sash through a step adjust adaptor secured to a hinge side member of the sash and extending along at least one of its inner and outer faces. The step adjust adaptor interfaces with the U-sweep member through a series of spaced apart detents which may be ridges and grooves to provide incremental adjustment of the breadth of the door. An L-sweeper is securable to a bottom member of the sash and is adjustable to vary a length (height) of the door.

A mountable interlock security device for securing first and second sliding articles slidable relative to each other from an open position to a closed position such that in the closed position the sliding articles have overlapping interior edges. The security device comprises a first component mountable to the first sliding article and a second component mountable to the interior edge of the second sliding article. The two components of the security device are mounted to the overlapping end regions of respective sliding articles such that when the sliding articles are in the closed position, the two components of the security device cooperate to limit lateral movement of the sliding articles. In another aspect, a method of retrofitting interior and exterior sliding articles, such as doors or windows, of a building with a security device is provided.

There are provided emergency exit window systems. In one form, there is provided an emergency exit window system that includes: a frame; a sash pivotally carried by the frame so as to pivot between a closed position in which the sash is flush with the frame, and an open position permitting human egress through the frame; and a locking mechanism adapted for locking the window sash in the closed position. The locking mechanism may include a locking arm movably carried by the sash, wherein the locking arm is movable relative to the sash between a lock position and an unlock position. Further, the locking mechanism may include at least one biasing member acting between the locking arm and the sash to bias the locking arm toward the lock position; an inwardly projecting locking catch fixedly carried by the frame; and an inwardly projecting safety guard movably carried by the frame.
