800 mm Lock Extensions (#31469)

This hardware links the bottom and top corner locks in a French casement window. In addition to serving as a gear, the extension has a central bolt that locks into the right-sash keeper.

The length of this connector is governed by the height of the casement. The lock extension itself must be cut to 13.25 in. less than the unit's height:

Frame Height	Lock Extension Length
≥ 20 in. and < 33 in.	800 mm (31.5 in.)
≥ 33 in. and < 41 in.	1000 mm (39.4 in.)
≥ 41 in. and < 59 in.	1460 mm (57.5 in.)
≥ 59 in. and ≤ 72 in.	1920 mm (75.6 in.)
