• Product Description

  The GS-38 gray garage door guide seal is designed to help close gaps along the sides of compatible sectional and commercial overhead garage doors. It installs over a matching guide angle to create a flexible contact point against the door, helping reduce drafts, dust, moisture, light, and outdoor debris around the opening.

  This guide seal fits compatible angle measuring approximately 1/4 inch to 3/8 inch and is supplied in 8-foot-6-inch lengths. Its gray finish provides a neutral appearance that blends well with many commercial, industrial, and residential garage door installations.

  The GS-38 profile is commonly used for replacing worn, cracked, hardened, or missing reverse-angle and guide weather seal.

  Compatibility & Fitment

  This GS-38 guide seal is designed to fit compatible guide or reverse angle measuring approximately 1/4 inch to 3/8 inch thick.

  Compatibility depends on:

  • Existing guide-seal profile
  • Angle thickness
  • Seal mounting direction
  • Door and track configuration
  • Required seal length
  • Existing retainer or guide assembly

  Compare the profile and mounting channel of the existing seal before ordering. The GS-38 designation should match the original seal whenever possible.

  Important Matching Notes

  Garage door guide seals are available in different profiles, mounting styles, and angle-size ranges. Similar-looking seals may not fit the same hardware.

  Before ordering, verify:

  • Existing seal profile
  • Angle thickness
  • Overall seal length
  • Seal color
  • Mounting direction
  • Door opening configuration

  This seal fits compatible 1/4-inch to 3/8-inch angle and measures 8 feet 6 inches long.

  The listed package quantity is 20 lengths per box. Confirm the quantity required for your installation before ordering.

  Installation Notes

  Remove the existing seal and clean dirt, rust, adhesive residue, and loose material from the guide angle before installation.

  Beginning at one end of the angle, press or slide the GS-38 seal into position according to the original installation method. Avoid stretching the seal during installation, as stretched material may shrink and leave gaps after installation.

  Trim excess material only after the seal is fully positioned. Confirm that the flexible edge makes consistent contact with the closed door without creating excessive drag.

  After installation:

  • Close the garage door and inspect the full seal line
  • Check for visible gaps or daylight
  • Confirm that the seal does not interfere with the rollers
  • Verify that the door moves freely
  • Adjust the guide angle when necessary for even contact

  Safety Warning

  Disconnect the automatic garage door opener before working near the track or guide assembly.

  Do not loosen track supports, bottom brackets, lift cables, springs, cable drums, or other components under tension. Garage doors are heavy, and improperly adjusted track or guide hardware can cause the door to bind or leave the track.

  Commercial and industrial door repairs should be performed by a trained garage door technician when track adjustment or structural hardware removal is required.
