Roll Lite / US Door Roll-Up Door Bottom Seal - 3/8" T, 1" Bulb, Black, 100' Roll | RL-LIT-BLB-KIT100

This 100-ft roll of black astragal bulb weatherstripping is used to replace worn, cracked, flattened, or missing bottom seal on compatible Roll Lite, US Door, U-Haul, and other roll-up doors. It fits doors that use a 3/8" T-style bottom retainer and a 1" bulb seal profile.

The 100-ft roll is a practical option for maintenance teams, contractors, and facilities replacing seal across multiple doors or cutting custom lengths in the field. This seal is commonly used on self-storage and mini-warehouse roll-up doors, as well as other compatible overhead doors that use an equivalent seal profile. Review the measurements shown on the product page, or order a sample to confirm fit before purchasing full rolls. This seal is made in the USA.

Installation Notes

• Remove the old bottom seal and clean dirt or debris from the retainer before installing the new seal.
• Check the retainer for crushed, bent, or pinched areas and straighten as needed.
• Cut the new seal slightly longer than needed, then trim to final length after installation.
• If needed, use a small amount of plastic-safe, non-staining lubricant in the retainer to help the seal slide through the track.
• Keep lubricants away from visible painted surfaces, hasps, latch areas, and any areas that may be repainted later.
• Avoid pulling with excessive force, which may stretch or damage the seal.
• Lightly crimp the track ends if needed to help reduce seal movement after installation.

This replacement seal may also be referred to as astragal, bulb seal, bottom seal, bottom weather seal, or roll-up door weather stripping. It helps reduce drafts, light gaps, dust, pests, and light water spray at the bottom of compatible doors.
