SecureIt Window and Door Locks (2)

Just stick this huge suction "star" on the stationary portion of your sliding glass door to prevent the sliding door from opening at all, or to allow some fresh air in without compromising security. The hefty 4"-dia., 2"-thick star is held in place by a big, strong 3-3⁄8"-dia. suction cup. Use on sash windows too, and can also be used as a handle to operate windows, or as a hook to hang decorations on windows or hang items in a shower. Pull tab to remove. Colors may vary. You get two.
