Pemko 085572 Door Sweep Brush Seal 48 Inch Nylon

Product Description

The PEMKO 085572 is a bristle-style door sweep and seal strip designed to block air, dust, light, and pests at the threshold gap beneath commercial and residential doors. The sweep uses nylon bristles measuring 0.625 inches in length, mounted to a back strip brush that is 0.25 inches wide. The overall usable length is 48 inches, making it suitable for standard single-door applications. This type of door seal is typically installed by door hardware specialists, general contractors, or facilities maintenance personnel as part of weatherization or code-compliance work.

This sweep is suited for use on commercial hollow-metal doors, wood doors, and similar door assemblies where threshold gap sealing is required. It is commonly installed in commercial office buildings, schools, healthcare facilities, and residential entryways. The nylon bristle construction allows the sweep to flex against irregular floor surfaces including tile, hardwood, carpet, and concrete, maintaining consistent contact across the full door width.

Key Features

• Nylon bristles resist moisture, debris, and repeated door cycling without significant wear
• Bristle length of 0.625 inches accommodates moderate threshold gap clearances
• Back strip brush width of 0.25 inches allows mounting in tight door frame conditions
• 48-inch length fits standard single-door applications and can be field-cut to size
• Flexible bristle design maintains contact on uneven or textured floor surfaces

Compatibility

Designed as an OEM-style replacement or new-installation sweep for standard 48-inch commercial and residential door assemblies requiring bristle-style threshold sealing.

Installation Notes

Installation is typically performed by a door hardware technician, carpenter, or facilities maintenance worker. Before installation, ensure the door is in the closed position and measure the threshold gap to confirm bristle length is appropriate. Fasteners are typically screws driven through the back strip into the door face or bottom rail — do not overtighten, as this can bow the strip and reduce bristle contact. Field-cutting to length should be done with a fine-tooth saw or aviation snips for a clean edge.
