Top Selection Recommendations
- For Maximum Accessibility: The NGP R50 Low-Profile Ramp is perfect for small 1/2" transitions in storefronts.
- For High-Traffic Entrances: Use the Pemko 270A or Hager 413SA Saddle Threshold for a durable, BHMA-certified aluminum transition.

Commercial Door Thresholds & ADA Ramps
Our ADA-compliant thresholds and interlocking ramps provide a safe, barrier-free transition for any commercial facility. From standard saddle thresholds to specialized thermal break systems, these products are engineered to withstand heavy foot and cart traffic while meeting strict height requirements (max 1/2"). For larger elevation changes, our modular interlocking ADA ramps allow for a precise 1:12 slope ratio, ensuring full accessibility. Available in slip-resistant finishes from NGP, Pemko, and Hager, these solutions insulate your building while providing a level sealing surface.
Sill Sweeps
Sill sweeps are the most cost-effective solution for sealing the gap between the door and the floor against drafts, moisture, and pests. Our surface-mounted commercial sweeps feature heavy-duty aluminum housings with high-performance inserts like silicone, neoprene, or nylon brushes. These are ideal for retail storefronts and industrial outswing doors where a simple, durable weather seal is required to reduce energy costs and improve occupant comfort.
Automatic Door Bottoms (ADB)
For superior sound control and a high-performance seal without the drag, automatic door bottoms (ADBs) are the professional choice. These units feature a spring-action concealed plunger that drops a heavy-duty seal only when the door is closed, providing an airtight fit for STC (acoustic) and smoke ratings. We stock surface-mounted, semi-mortised, and full-mortised models from NGP and Pemko, making them perfect for hospitals, luxury hotels, and private office suites.
Door Bottoms (Shoes)
Often called U-shaped door shoes, these bottoms wrap around the bottom edge of the door to provide 360-degree protection and a superior seal. Unlike standard sweeps, door shoes encase the bottom rail, protecting the door material from moisture and physical damage while providing multiple "fingered" seals to block airflow. These are the preferred choice for heavy-use exterior doors where durability and a clean, integrated look are top priorities.
