Abstract
An adjustable stop is adapted to limit travel of a sliding sash window/door, and can be installed upon the window/door master frame during initial manufacturing of the product, or may be an after-market option added at some time after manufacturing was completed. The stop may even be installed upon sash windows/doors currently in service in a building. The stop is intended to limit sash travel between a closed position and a safe position, where the safe position is a position significantly less than a full-open position. The safety stop may be comprised of a housing and a tumbler being pivotally mounted within a cavity in the housing, with a spring to bias the tumbler out of an opening in the housing. Mounting is by a flange extending from the housing, with spacers of varying thickness that are capable of removably attaching thereon to accommodate sash to master frame height differences.
