Install only on clean, dry concrete at temperatures above 40ºF (5ºC)

Remove existing weatherstripping from door bottom

Not recommended for installation on asphalt, painted or treated surfaces, broken concrete or gravel

Tape measure, utility knife and pencil

Installation instructions:

1. With garage door open, center threshold between the garage door track (the channel the door rollers

ride in). Trim to length with utility knife. (The “hump” side should on the inside side of the door.)

2. Lower the garage door on top of the threshold’s 2-inch level strip. Push the 45º hump against the

back of the bottom of the garage door. Note: Notch threshold around door jambs, if necessary, to ensure

the 45º hump is against the back of the bottom of the garage door.

3. With the pencil, mark the inside edge of the threshold on the floor the full length of the threshold

(from one door jamb to the other).

4. Carefully raise the door (without moving the threshold) and mark the outside edge of the threshold

the length of the door.

5. Remove the threshold and apply three rows of adhesive the full length of the door between the pencil

lines.

6. Replace the threshold between the pencil lines and firmly press into place. Carefully apply pressure

to the threshold to ensure the adhesive spreads uniformly.

7. Inspect the threshold to make sure it is still between the pencil lines. The position can slightly adjusted

for a short period of time. The length of time varies depending on ambient conditions.

8. Close the garage door to keep constant pressure on the threshold for twenty four (24) hours.
