Our NSCD garage door threshold seal kit from North Shore Commercial Door is a premium weather seal for commercial or residential garages at a budget price. This garage door water barrier also keeps out pests, dust, dirt and other contaminants. Glue is included to secure your weather seal to the garage door threshold immediately beneath the bottom of the garage door, creating a seal that closes gaps. It's sold by the foot, so you won't have to order more than you need. We advise that you add an extra foot to the length you want to accommodate shrinkage,

Protect your garage's contents from the elements with a seal that will also save you money on energy bills by blocking hot and cold drafts. This tough North Shore Commercial Door brand threshold seal has been tested to confirm it won't crack or shatter when repeatedly driven over by vehicles. The black garage door weather seal threshold also meets California Fire Marshall and CPAI-84 standards for flame resistance. The NSCD-THSB seal will remain flexible from 40 degrees below zero to 150 degrees Fahrenheit, making this kit ideal for any climate. The threshold seal is 3 1/8 inches wide and a half-inch high at its tallest point. It's an economical choice over similar Clopay, Sensible Solutions and Storm Shield brands.

Installation Instructions for Garage Door Threshold Weather Seal Kit:

  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 be 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 edges 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 be 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. ALLOW AT LEAST 24 HOURS FOR ADHESIVE TO DRY BEFORE DRIVING OVER.
