STOP DEVICE FOR LEFT & RIGHT HAND SLIDING DOORS
A stop device for sliding doors or windows is described, wherein the device has a block member secured to the lower end of the sliding door so that the block member forms an appendage to the door and lying substantially within the plane of the door. The block member is formed symmetrical about a horizontal plane so that it can be used with either right or left-hand sliding doors, and has a vertical bore wherein a bolt or pin is disposed. Communicating with the bore is a horizontally disposed hole lying substantially on the horizontal plane. Within the hole is an inwardly biased steel ball. The bolt has two axially spaced circumferential grooves that are singularly engaged by the steel ball to provide predetermined stops for the bolt. The bolt can be inserted within the bore from either end.
