Abstract
A lock for a sliding panel such as a sliding glass door includes a chain which bends in only one direction. The chain, when latched, forms an incompressible column between the openward edge of the panel and the door frame. Unlatching allows the chain to bend in its allowed direction and fall vertically along side the door frame, thus allowing the panel to open.
