Abstract
A sweep lock locking the check rails of an upper and lower sash improves window resistance to negative wind force. The lock accomplishes this by a cam with a locking rim that extends both upward and downward to engage cam receiver projections above and below the locking rim to lock along two vertically separated locking lines, which tends to resist sash tilting from vertical as sash are deformed in response to negative wind force. Preferred embodiments of a cam lock and mounting hub include a two-piece hub that snaps together within a rotational opening of the cam lock to form a subassembly ready for mounting.
