Improve the seal along the bottom of commercial doors with the Reese 963BLK-36 Door Sweep.

Designed for commercial and institutional openings, this heavy-duty sweep combines a durable black anodized aluminum holder with a flexible 2" black nylon brush that conforms to uneven floor and threshold surfaces.

• Insects

• Light infiltration through the door-bottom gap
