Thermwell RV18 Vinyl Garage Door Bottom Weather Seal

Product Description

The THERMWELL RV18 is a vinyl replacement bottom weather seal designed for metal overhead garage doors. Measuring 2.75 inches wide and 18 feet long, this black vinyl strip installs into the bottom retainer of most metal overhead garage door sections, replacing the worn or cracked insert that allows air, water, and debris to pass through. Licensed contractors, garage door technicians, and experienced DIYers install this seal as part of routine door maintenance or seasonal weatherproofing work. The flexible vinyl construction conforms to uneven floor surfaces to maintain a consistent barrier against drafts, dust, dirt, and water infiltration.

This seal is suited for residential metal overhead garage doors where the bottom retainer channel accepts a standard T-style or bulb-style vinyl insert. It is commonly installed in attached and detached residential garages as a direct replacement for deteriorated factory seals. The 18-foot length accommodates most standard single and double garage door widths without requiring splicing on typical installations. Six units are packaged per case, making it practical for contractors servicing multiple doors on the same job.

Installation Notes

Installation is typically performed by a garage door technician or a knowledgeable DIYer with basic hand tools. Disengage the garage door opener and ensure the door is fully closed and secured before removing the old seal. Slide the worn vinyl insert out of the retainer channel from one end and feed the new RV18 seal in from the same end, trimming any excess length with a utility knife. Inspect the retainer channel for damage or corrosion before installing the new seal to ensure a secure fit.
