SecuraSeal Sliding Patio Door

Anyone who has ever had a sliding patio door knows the drill: The lock latches at a single, easily jimmied point, so real security requires keeping a broomstick or dowel rod stowed in the track of the door. The SecuraSeal Sliding Patio Door turns the entire 76-inch floor-to-ceiling edge of the door into a single, sturdy locking mechanism. The groove along the door's edge surrounds an expandable flange in the doorjamb. A switch on the jamb (rather than the door handle) engages the lock, further thwarting any attempt to disengage the lock from the outside.
