Barzen Aluminum Threshold Strip — Exterior, 5″ Wide
This Barzen threshold is designed for exterior doorways with ADA wheel-chair compliance in mind. It uses a robust aluminum body (3.3 mm thick) to withstand outdoor conditions and heavy traffic. Pre-drilled holes enable straightforward installation for a DIY project. The 5″ width and 1/4″ height deliver a low-profile transition while maintaining barrier-free access. This option is best for exterior doors where durability and a clean look matter most.
Best for: Exterior entrances with wheelchair access needs in residential or light commercial settings. Choose this if you want a slim profile that still meets ADA criteria and can be installed with simple hardware.
Caution: Confirm the doorway clearance before installation, as the 1/4″ height may require floor prep to ensure a flush fit with certain flooring transitions.
JELOSTONE 6″ Threshold, Commercial Aluminum Threshold
This premium metal threshold offers a 6″ width with a 1/4″ height, giving a substantial transition strip suitable for exterior commercial doorways. UL-certified and available in 36″ and 48″ lengths, it provides flexible sizing to fit various doorway widths. It helps seal under doors, reducing drafts and dust ingress, and is designed for durable barrier-free performance.
Best for: Commercial entrances or large residential doors that require a wider threshold for accessibility and weather resistance. Opt for this if you need versatile length options and robust weather sealing.
Caution: The broader width may require more floor space clearance; verify door swing and casing before purchasing.
Randall 36″ X 8″ Wide Heavy‑Duty Threshold
Randall Manufacturing’s 36″ long, 8″ wide, 1/2″ high threshold is built for heavy traffic in both residential and commercial environments. The heavy‑duty construction supports high-traffic doors and helps seal gaps to block drafts and moisture. It’s ADA accessible, making it a solid choice for doorways that require rigorous accessibility standards and durable performance.
Best for: High-traffic doors in commercial settings or busy home entryways where a wide, sturdy threshold is needed. Choose this if you prioritize durability and accessibility in a single piece.
Caution: The wide profile may require additional floor space clearance; ensure the door can fully clear the threshold when opened.
JELOSTONE 5”W x 1/2”H x 36”L Heavy-Duty Threshold
This JELOSTONE model offers a 5″ width and 1/2″ height, designed for heavy-duty applications with ADA accessibility and fire-rated considerations.

Best for: Doors requiring a robust barrier-free transition that also adheres to fire-rated and ADA standards. Opt for this if you need a balance of durability and risk mitigation against drafts and pests.

It’s designed for ADA accessibility and barrier-free use, and it carries a fire-rated design profile for added safety. The matte black anodized finish provides a clean, professional look for commercial and residential doors alike.
Best for: Large doorways where a sturdy, ADA-compliant threshold is needed and where a fire-rated option is desirable. Choose this for high-traffic entries that demand long-term durability.
Caution: Ensure the door’s bottom rail is compatible with the threshold height to prevent binding during operation.
Buying Guide: Choosing The Right ADA Door Threshold
- Traffic and location: Exterior thresholds face weather and debris; interior thresholds focus on accessibility and protection from drafts. Match thickness, height, and material to the environment.
- Width and height: Wider thresholds (6″–8″) offer more coverage but may need more clearance. Choose 1/4″ to 1/2″ heights to balance wheel-chair access and door clearance.
- Material durability: Aluminum thresholds are common for durability and corrosion resistance. Look for heavy-gauge construction for high-traffic doors.
- Accessibility compliance: Ensure ADA compatibility for smooth wheelchair passage; verify if the threshold supports barrier-free use without creating tripping hazards.
- Installation and maintenance: Pre-drilled holes and included screws simplify mounting. Consider whether trimming is needed for precise fit and flush transitions.
- Fire-rated and weather-sealing: If the doorway impacts fire safety or insulation, select thresholds that offer fire-rating and effective weather sealing.
