Thermwell C35PH White Plastic Brush Door Sweep

Product Description

The THERMWELL C35PH is a white plastic and brush door sweep designed to seal the gap between the bottom of a door and the threshold. Measuring 1.75 inches wide by 36 inches long, it blocks drafts, dust, insects, and light from passing under exterior or interior doors. The sweep combines a rigid plastic mounting channel with a flexible brush strip that conforms to uneven floor surfaces and maintains contact through repeated door cycles. This type of hardware is typically installed by general contractors, property maintenance techs, or experienced DIYers as part of weatherization or energy-efficiency work.

The C35PH suits standard 36-inch residential and light commercial doors. It works on wood, steel, and fiberglass door bottoms and is appropriate for use on exterior entry doors, utility room doors, and garage-to-home passage doors where draft and pest control are priorities. The white finish is a common match for painted or vinyl-clad door bottoms in residential settings.

Installation Notes

Installation is a general carpentry task requiring a tape measure, drill or screwdriver, and optionally a hacksaw if the sweep needs to be trimmed to a shorter door width. Close and latch the door before marking screw positions to ensure the brush strip seats correctly against the floor. Follow local building code requirements for weatherstripping on exterior doors when applicable to energy compliance inspections.
