This garage door bottom threshold seal is integrally molded from premium PVC. It withstands extreme temperatures ranging from -40°F to 284°F. It resists cracking and deformation under long-term sun and rain exposure and stays intact under heavy rolling pressure. A yellow warning strip on the surface improves visibility at night, and anti-slip textured ridges reduce slipping hazards. The serrated base grips tightly to the floor and bonds firmly with adhesive. It effectively keeps rainwater, snow, dust and leaves out of the garage to keep the floor dry and clean. The maximum length reaches 20 ft. and can be cut freely according to doorway width. It adheres securely to concrete, asphalt and painted flooring. Highly versatile, this seal works not only for residential garage doors but also for warehouses, factories and storefronts to block outdoor debris and moisture infiltration.
