Commercial Door Bottoms, Sill Sweeps & Automatic Door Bottoms (ADB)
Achieve a total perimeter seal with our professional-grade commercial door bottoms and sill sweeps. Designed for high-traffic storefronts, hospitals, and industrial facilities, these solutions are the primary defense against energy loss, sound transmission, and smoke infiltration. We stock a comprehensive range of Grade 1 products from industry leaders like NGP (National Guard Products), Pemko, and Hager, ensuring your facility meets all ADA compliance and UL fire-safety standards.
Whether you need a cost-effective surface-mounted sweep for weatherproofing or a high-performance automatic door bottom (ADB) for acoustic privacy, our selection is engineered for durability and ease of installation. While these units typically ship with standard fasteners, we recommend using Tapcons for masonry sills. To prevent frost-heave and moisture expansion in cold climates, always seal the exterior edge with outdoor-rated silicone caulk to ensure the door remains free-swinging and secure year-round.

Door Bottoms
Our commercial door bottoms (also known as door shoes) wrap around the bottom of the door to provide a 360-degree seal. These are preferred for heavy-use exterior doors where a standard sweep might be kicked or damaged. By encasing the door edge, these U-shaped door shoes protect the door material from moisture while maintaining a clean, professional appearance that meets ADA clearance requirements.
Automatic Door Bottoms (ADBs)
For the ultimate seal without the drag, automatic door bottoms (ADBs) are the engineered choice for high-end commercial openings. These "spring-action" seals feature a concealed plunger that drops the gasket only when the door is closed, providing a tight fit against the threshold for STC (sound) and smoke ratings. Available in surface-mounted, semi-mortised, or full-mortised profiles from NGP and Pemko, these units are ideal for luxury hotels, hospitals, and office privacy.
Sill Sweeps
Sill sweeps are the primary defense against drafts, moisture, and pests. Our selection of commercial door sweeps features heavy-duty aluminum housings with durable neoprene, silicone, or nylon brush inserts. These surface-mounted seals are field-sizable and provide an immediate, cost-effective solution for increasing energy efficiency in retail and industrial storefronts.
