PLEASE MEASURE THE THICKNESS OF YOUR DOOR. Works on most hinged doors up to 1 3/8" thick, including interior and exterior doors, French doors and double doors. Works on doors with levers, knobs, and even large or uniquely shaped handles. 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. Also does NOT work on metal door frames, patio screen doors, storm doors or double doors that swing BOTH ways.

REQUIRES ONE SCREW (INCLUDED) TO BE DRILLED INTO YOUR DOOR FRAME. If you are installing on an exterior door that opens inward into your home, please note the screw will be drilled on the exterior/outside part of your door frame. The GlideLok has holes for the possible attachment of a hook or rod (NOT INCLUDED), which is helpful for especially tall doors / shorter adults. If you do not attach a rod, you must be able to reach the top of your door to slide the GlideLok back and forth.

DURABLE METAL WON’T CRACK OR BEND LIKE CHEAP PLASTIC MODELS. GlideLok is the only top-of-door childproofing system of its kind made of high-quality painted metal, not flimsy plastic. So it will last you for years keeping toddlers from opening doors to unsafe areas in your home. The GlideLok makes your life easier and - most importantly - keeps your little ones safe.

RESTS ON TOP OF THE DOOR SO KIDS CAN’T REACH IT. Unlike door knob covers or other door lever locks, the GlideLok sits on top of your door, so it’s completely out of reach and your child can’t dismantle it. It is also unobtrusive and blends in with your décor. Most people won’t even realize it’s there.

ADULTS CAN CONVENIENTLY LOCK AND UNLOCK THE DOOR FROM BOTH SIDES. Unlike other types of door lever handle locks, you will not get trapped in a room while your child wanders around the house alone. Adults can operate this lock from both sides of the door. Also, if you don’t need it locked for a period of time, simply leave the GlideLok disengaged and you won’t have to unlock every time.
