Abstract: Channel reinforcements configured to move between open and closed location along with a window sash are described herein. The channel reinforcements may provide reinforcement to window jambs proximate the latch bolts that extend into jamb channels in the window jambs. The channel reinforcements may be coupled or uncoupled to the balances located in the window jambs.

Abstract: An exemplary tilt latch mechanism including a latch bolt configured to rotate about a bolt axis to locate a portion of the latch bolt adjacent a portion of a latch, or jamb, channel for support is described herein. The latch bolt may include a foot portion configured to, e.g., distribute forces within the latch channel.

Abstract: A window has a frame and a movable sash mounted within the frame. The sash is formed from interconnected lineals bounding a glazing unit with at least one of the lineals being a sash rail made of a substantially hollow extrusion. A sash lock is mounted to the sash rail by means of a pair of toggle anchors projecting from the sash lock into the sash rail. A corresponding pair of lock screws is driven through the toggle anchors causing them to spread apart within the rail to form a mechanical lock that fixes the sash lock securely to the sash rail. More broadly, a component is anchored to an extrusion, which may be substantially hollow, with toggle anchors extending through holes in the extrusion and being spread apart within the holes by a screw.
