Thermwell B59/36H Door Bottom Seal 1-5/8x36 Bronze

Product Description

The THERMWELL B59/36H is a bronze aluminum and vinyl door bottom seal designed to close the gap between a door and an uneven or irregular floor surface. The extruded aluminum body provides structural rigidity while the vinyl insert compresses against the floor to form a consistent draft and dust barrier. Measuring 1-5/8 inches tall by 36 inches wide, this door bottom is sized for standard residential and light commercial entry doors. Installation is straightforward and does not require specialty tools, making it a practical choice for general contractors, carpenters, and maintenance technicians.

This door bottom is suited for residential entry doors, interior passage doors, and light commercial applications where floor surfaces are uneven, out of level, or subject to settling. The adjustable design allows the installer to fine-tune the vinyl contact pressure after mounting, accommodating minor variations in floor height across the door sweep. The bronze finish blends with standard door hardware in both residential and commercial settings.

Compatibility

Installation Notes

Installation is typically performed by a carpenter, general contractor, or experienced maintenance technician. The door should be removed from its hinges or held stationary before fitting and fastening the door bottom. Adjust the vinyl sweep contact against the floor surface before final screw tightening to ensure an even seal without binding door operation. Field-cut the aluminum extrusion to width with a fine-tooth metal saw if the door opening is narrower than 36 inches.
