Flat Door Thresholds
Flat Door Thresholds and Low-Profile Door Sills
Flat door thresholds provide a smooth, low-profile transition between adjoining floor surfaces while helping protect doorways from everyday foot traffic and wear. Also known as flat utility door thresholds or door threshold plates, they are commonly used in offices, schools, hospitals, warehouses, and residential properties. These interior door thresholds are available in different profiles to accommodate various flooring heights and doorway requirements, including flush and sloped door threshold designs.
TM Hardware offers a range of flat door thresholds, low-profile door thresholds, and door transition plates in aluminum, stainless steel, and other durable materials. Available in multiple widths, heights, and finishes, our selection includes flat threshold plates and door floor plates for commercial and residential applications, with options for non-slip surfaces and custom sizing.

Commercial & Residential Flat Door Thresholds
Flat utility door thresholds span the area beneath a doorway to help create a smooth transition between flooring surfaces while protecting high-traffic openings from daily wear. They are commonly installed in commercial buildings, healthcare facilities, schools, apartment complexes, industrial facilities, and residential properties where durability and accessibility are important.
Available in aluminum, stainless steel, brass, and other heavy-duty materials, flat thresholds are designed to withstand constant foot traffic, carts, equipment movement, and environmental exposure. Many models feature abrasive or non-slip surfaces to improve safety in wet or high-use environments.
Flat thresholds can also help improve the performance of door sealing systems by providing a stable contact surface for door bottoms, door sweeps, and automatic door bottoms. When combined with the proper weatherstripping and sealing products, they can help reduce drafts, moisture infiltration, dust, insects, and unwanted air leakage.
For applications requiring enhanced weather protection or a more secure seal, consider our Interlocking Thresholds, which are designed to work together with compatible door bottoms to create a tighter seal against air and water infiltration.

Frequently Asked Questions
What is a flat door threshold?
A flat door threshold is a low-profile sill installed beneath a doorway to create a smooth transition between floor surfaces and provide a durable walking surface.
Where are flat thresholds commonly used?
Flat thresholds are frequently installed in commercial buildings, schools, hospitals, warehouses, retail stores, and residential properties where accessibility and durability are important.
Are flat thresholds ADA compliant?
Many flat threshold models are designed to support ADA accessibility requirements. Always verify the specific dimensions and installation requirements for your project.
What materials are available?
Flat thresholds are commonly manufactured from aluminum, stainless steel, brass, bronze, and other heavy-duty materials depending on the application requirements.
Can thresholds be custom cut?
Yes. Many flat door thresholds can be supplied in custom lengths to ensure an accurate fit for your doorway.
How do I choose the correct threshold?
The ideal threshold depends on doorway width, floor conditions, traffic levels, accessibility requirements, and whether weather protection is needed. Interlocking threshold systems may be a better option for exterior openings requiring enhanced sealing performance.
