Thermwell A79/36A Aluminum Door Bottom Sweep 2x36 Brushed Chrome

Product Description

The THERMWELL A79/36A is a heavy-duty aluminum door bottom sweep designed to seal the gap between a door and its threshold. The extruded aluminum body carries a reinforced rubber sweep that compresses against the floor surface to block drafts, dust, insects, and moisture. The brushed chrome finish suits both residential and light commercial applications. Slotted mounting holes allow horizontal adjustment so installers can dial in a flush fit without cutting or shimming. The sweep seals gaps up to 0.75 inches, making it suitable for doors that have settled or sit on uneven thresholds. Weatherization contractors, carpenters, and facility maintenance techs are the primary installers.

This door bottom is intended for use on standard interior or exterior doors where air infiltration, noise, or pest entry is a concern. It is commonly installed on entry doors, utility room doors, and commercial suite doors. The 2-inch height and 36-inch length fit a wide range of standard door widths, and the slotted holes allow the unit to be positioned correctly before final fastening. The brushed chrome finish coordinates with most commercial-grade door hardware. Units are sold individually within a package quantity of 12.

Installation Notes

Installation is typically performed by a carpenter, weatherization technician, or qualified maintenance professional. Before installing, confirm the door swings freely and the threshold surface is clean and level. Position the sweep against the closed door, align using the slotted holes, and fasten with appropriate screws to the door face. Check that the rubber sweep contacts the threshold evenly across the full width without binding the door swing.
