The Hager 403S is a premium, ultra-low profile flat saddle threshold designed for applications where a minimal floor transition is essential. With a 4-inch width and a sleek 1/4-inch height, this threshold provides a clean, unobtrusive bridge between flooring surfaces. Constructed from high-strength extruded mill aluminum, the 403S is built to withstand heavy foot traffic while maintaining the structural integrity required for commercial and industrial entryways.
Maximum Accessibility and Safety
The Hager 403S is the gold standard for barrier-free design. At only 1/4-inch high, it offers one of the lowest profiles in the industry, making it fully ADA compliant. This ensures safe and effortless passage for wheelchairs, walkers, and medical carts, making it an ideal choice for hospitals, schools, and assisted living facilities. The surface features a fluted, slip-resistant pattern that provides critical traction, reducing the risk of accidents in high-traffic retail or office environments.
Versatile Engineering for Modern Openings
The mill finish aluminum construction is naturally corrosion-resistant, ensuring a long service life in both interior and exterior settings. Because of its flat, low-profile design, it is perfectly suited for use with automatic door bottoms or sill sweeps, allowing for a tight environmental seal without the trip hazard of a standard high-profile sill. Each unit is furnished with heavy-duty #10 x 1-1/2" wood screws to ensure a permanent and stable mount to wood subfloors.
