US Patent 11993956 Sliding door foot bolt

A lock kit for a fenestration assembly includes a panel stop. The fenestration assembly includes a first panel and a second panel, at least one of the first and second panels being slideable relative the other of the first and second panels. The panel stop is configured to pivotably mount within a recess of a frame member of the first panel and pivot between a first stop position configured to maintain the first and second panels in a fully closed position, a second stop position configured to limit sliding of the first and second panels beyond a preset partially-open position, and a third position substantially within the recess, the third position being configured to not restrict a range of motion of the first and second panels.
