Endura Door Bottoms

Superior barrier against air and water.

Endura’s door bottoms offer a superior barrier against air and water.

Whether relying on our Leading Edge Bulb design with a fixed or adjustable sill, or the enhanced sealing power of the Z-Articulating Cap Sill™ Door Bottom with our auto-adjusting sill solution, Endura door bottoms keep sealing long after others fail. Traditional door sweep options also available.

With other “fin-only” door sweep products, there is only a thin line of contact against the sill, which leads to leaks over time or even right away if installation or site conditions aren’t perfect. Each Endura door bottom utilize a combination of fins and bulbs specially designed to work with Endura sill solutions for proven, unmatched protection against leaks and a larger sealing area.
