Installation Instructions + Troubleshooting


Pencil and drill



For doors up to 1-3/8" thick:
Leave the spacer bar attached.
For doors up to 1-13/16" thick: 
You may need to remove the spacer bar to fit the GlideLok on top of your door. Be sure to use a #1 Phillips drill bit only, as a larger bit will likely strip out the screw heads.

Place GlideLok Part C on top of your door with the U-shaped slot about 6" from the door edge over your door knob. The GlideLok screw (Part A) and peg (Part B) should be installed on the non-flush side of the door frame. (See picture above. The non-flush side does not show the hinges.) Remember, the GlideLok can still operate from BOTH sides of the door, regardless of which side the peg is on.

With the door closed, mark the door frame with a pencil lined up at the center of the U-shaped slot. "Test glide" the GlideLok before continuing. If GlideLok prevents door from closing, adjustments to the door may need to be made. (See troubleshooting tips starting at 1:24 of this video.)

To prevent wood damage, drill a 1/8" pilot hole into the door frame pencil mark.

Place the screw (Part A) into the peg (Part B). Screw the peg into the 1/8" hole from Step #4. Close the door, and the GlideLok U-shaped slot will slide easily onto the peg to secure the door.

How do I install the GlideLok on an exterior door?

The screw and peg will need to be installed outside, since they must go on the side of the door without the hinges. But that’s OK!

The GlideLok is not meant to be a security lock, and it is designed to open from BOTH sides of the door by an adult. That is what prevents you from being locked out accidentally, because many childproof door locks only lock / unlock from one side.

For most exterior doors, you will also need to remove the spacer bar (from GlideLok Part C) with an appropriate smaller-size (#1) Phillips drill bit. Apply gentle pressure so the screws will not strip.


What if I have to install the screw and peg on the wrong side of the door?

The screw and peg will always go on the side of the door WITHOUT the hinges. This will be the side where the door is NOT flush with the frame.

But remember, regardless of which side of the door the GlideLok must be installed on, an adult can still lock / unlock it from BOTH sides!


What if I can’t reach the top of my door to slide the GlideLok across?

GlideLok has holes for the possible attachment of a hook or rod (not included), which is helpful for especially tall doors / shorter adults.

A window blind rod with a snap hook on the end works best. Remember that you will need two (one for each side of the door.) These rods can be found at most hardware stores. See picture below for example.

Some customers also use a ladle or ruler to slide the GlideLok back and forth if they are not tall enough to reach the top of the door themselves.

What if I’m installing on French doors or double doors?

You will need one GlideLok for each door. If the two doors face each other (like double French doors), the GlideLok will be positioned the same way on each door. See example photos below.

Please be sure you have watched the full video above. At the end, we demonstrate the troubleshooting tips discussed here. It is much easier to understand on video!
If GlideLok does not glide smoothly on top of door ...
Rub a votive candle or other wax / lubricant on all contact points, including the underside of the GlideLok, the top of the door, and the door frame.

If space between door frame and top of door is too tight for GlideLok ...
Sand down the top of the door by just a millimeter to allow clearance for the GlideLok. Use 80-grit or lower sandpaper, or a belt sander will make it even easier.

If installing on door with weather stripping ...
Six inches of weather stripping may need to be removed before installing to allow the GlideLok to slide properly.

If door fits too tightly against frame ...
Insert small rubber bumper (like the clear adhesive cabinet bumpers) on top corner of door frame (over door knob) to allow space for the GlideLok.

If your door is too thick for the GlideLok ...
You may need to remove the spacer bar. Use an appropriate smaller size Phillips drill bit (#1), and apply gentle pressure so screws will not strip. The GlideLok will fit up to 1-13/16" thick doors with the spacer bar removed. 

If your door is too thin for the GlideLok ...
Try adding adhesive felt pads on the inside of the GlideLok to fill up the extra space.

If you have trouble with the GlideLok sliding too far in either direction ...
Peel and stick small rubber bumpers (like the clear adhesive cabinet bumpers) near the top of your door, in the spots where you want the GlideLok to stop sliding.

If the peg will not stay secure in the door frame ...
You may need to substitute a longer screw to work better with your particular door frame.
