The Hager 430SA is a specialized, extra-wide flat saddle threshold designed to provide a smooth, durable transition across expansive floor gaps. Featuring an impressive 7-inch width and an ultra-low 1/4-inch height, this threshold is the professional choice for wide commercial door frames, expansion joints, and transitions between differing floor materials. Crafted from high-strength extruded mill aluminum, the 430SA is engineered to withstand the rigors of heavy industrial and commercial traffic while maintaining a clean, architectural look.
Superior Accessibility for High-Traffic Entryways
Designed with mobility in mind, the Hager 430SA is fully ADA compliant. Its slim 1/4-inch profile creates a virtually seamless transition, making it ideal for hospital corridors, schools, and retail centers where wheelchairs, gurneys, and heavy carts are frequently used. The surface is detailed with a fluted, slip-resistant pattern to ensure maximum traction for pedestrians. Its wide footprint provides exceptional stability, ensuring the threshold remains secure even under the pressure of heavy dolly or pallet jack traffic.
Versatile Protection and Professional Installation
The mill finish aluminum construction offers natural corrosion resistance, making it suitable for both interior office spaces and exterior perimeters. Its flat profile makes it an excellent companion for automatic door bottoms or sill sweeps, allowing for a perfect environmental seal without the trip hazard of a high-profile sill. Each unit is furnished with high-quality #10 x 1-1/2" wood screws for a secure, permanent mount to wood subfloors.
