Prime Line Products T 8680 Storm Door Bottom Sweep 37in

Product Description

The PRIME LINE PRODUCTS T 8680 is a T-shape gray vinyl bottom sweep designed to seal the base of storm doors against air infiltration. Measuring 37 inches in length, 1/2 inch in height, and 1/4 inch in top width, this sweep installs along the bottom edge of a storm door to block drafts, dust, and light air intrusion at the threshold. It ships in a package of 10 units, making it a practical stock item for contractors and door service technicians who handle multiple door installs or replacements in a single job run.

This bottom sweep is intended for use on residential and light commercial storm doors where a T-slot or compatible bottom rail channel accepts a T-profile insert. It functions as a bottom seal, sitting flush against the threshold surface when the door is closed to minimize conditioned air loss. Installers working on weatherization upgrades or door replacement projects will find the 37-inch length suitable for standard storm door widths before field trimming to final fit.

Compatibility

Designed as an OEM-style replacement bottom sweep for storm doors equipped with a T-slot bottom rail channel that accepts a 1/4-inch top-width T-profile insert.

Installation Notes

Installation is typically performed by a door installer, glazier, or general contractor. Before replacing the sweep, ensure the door is closed and stable, and remove any existing sweep or worn insert from the bottom rail channel. Slide or press the T-profile into the channel and trim to length with a utility knife or tin snips as needed. Verify the sweep makes even contact with the threshold across the full door width after installation.
