GlideLok Durable Metal Top-of-Door Childrens Baby Safety Lock for Childproofing

Tired of childproofing door locks that don't work? Imagine being able to cook dinner or pay bills without constantly getting interrupted by your little one entering an off-limits room. Your childproofing frustrations will soon be over: Will the GlideLok work for your door? The GlideLok works on most standard interior and exterior doors with hinges, including French doors and double doors. Your door must be 1-3/8 inches thick or less to install the GlideLok without removing the spacer bar. Your door can be up to 1-13/16 inches thick if you remove the spacer bar with a #1 Phillips drill bit. Please measure the thickness of your door before ordering. This product does not work on any type of sliding door on a track, such as bifold doors, pocket doors, sliding glass doors, or sliding decorative barn doors. It also does NOT work on metal door frames, patio screen doors, storm doors, or double swing doors (that swing both ways).
