Smooth Thresholds

3 | 4 |
Easy to mop and wipe down, these smooth thresholds don't have ridges or grooves that can trap water and dirt. They're often used to transition between different flooring surfaces and reduce the gap between a door and the floor. Because they’re smooth, they provide less traction than ribbed thresholds. Cut them with a hacksaw for a precise fit.
Vinyl Rubber—Vinyl rubber thresholds insulate against heat and cold. Glue them in place—no fasteners or drilling required.
Aluminum—Aluminum thresholds are lightweight yet durable. They won’t corrode from the weather, so they can be installed in exterior doorways. They’re easier to cut than stainless steel thresholds and they're easy to clean.
304 Stainless Steel—304 stainless steel thresholds resist corrosion better than aluminum thresholds. Often installed in clean rooms and food processing areas, they stand up to frequent washings and mild chemical cleanings. Stronger and harder than vinyl rubber and aluminum, these thresholds last longer and are more durable. However, they’re harder to cut.
ANSI/BHMA A156.21—ANSI- and BHMA-certified thresholds have been tested to withstand a 1,000 lb. compressive load.

Reversible Smooth/Ribbed Thresholds
 |
The middle of these three-piece thresholds can be installed smooth or ribbed side up. The smooth side has a groove-free surface that’s easy to clean, while the ribbed side is slip resistant. Use them to make a transition between flooring surfaces and to reduce the gap between a door and the floor. Made of aluminum, these thresholds are lightweight and durable. They won’t corrode when exposed to water or humidity, so you can install them in exterior doorways.
ANSI/BHMA A156.21—ANSI- and BHMA-certified thresholds have been tested to withstand a 1,000 lb. compressive load.
