The Commercial Door Worx DT101 Aluminum Door Threshold provides a durable, wide transition across compatible commercial doorway openings. Both DT101 models use a 5-inch-wide profile with a 1/2-inch rise and a commercial mill-finish aluminum surface. Choose a 36-inch threshold for a common single-door application or a 72-inch threshold for an appropriately sized wider opening or pair of doors.
Product Features
- Durable aluminum profile: Commercial-grade metal construction suitable for properly prepared interior or exterior door openings.
- Consistent cross-section: Both offered lengths are 5 inches wide and 1/2 inch high; only the factory length differs.
- Mill finish: Aluminum appearance for use with common commercial storefront, hollow metal and wood door hardware.
- Floor edge protection: Helps protect floor transitions against shoes, carts, hand trucks and typical commercial traffic.
- Replacement or new construction: Suitable for appropriately prepared commercial building entrances and maintenance projects.
- Field fitting: May be cut to the required opening length where permitted, with correct edge treatment, installation clearance and secure anchoring.

Where DT101 Thresholds Are Used
Commercial storefront entrances, retail and office doorways, institutional facilities, hospitals, schools, assisted-living buildings, service doors and properly specified industrial openings. Choose the length and profile that match the installed door sweep, bottom seal, closer and the adjoining floor levels.
Measurements and Installation Checklist
- Measure clear opening width: Determine the finished threshold length, including stops, jambs and any required field trimming.
- Check the floor transition: Confirm the existing slab and floor elevations permit a 1/2-inch-high, 5-inch-wide threshold without creating an unwanted trip edge.
- Accessibility review: A 1/2-inch rise is not automatically an approved accessible transition. Review required bevels, transition slopes and applicable accessibility criteria for the complete opening.
- Check exterior exposure: Provide appropriate sealing, drainage and water protection at exterior thresholds where specified by the door design.
- Confirm mounting hardware: Determine anchor type and spacing for the actual concrete, wood, masonry or other floor substrate.
- Verify door clearance: Confirm sweep contact, undercut, latch operation and swing clearance after installation.
Ordering Notes
This product family contains only the DT101 5 in × 1/2 in mill-finish profile, in two lengths. Other CDW 5-inch saddle thresholds with different rise and architectural finish combinations belong to a separately cataloged profile and should not be assumed interchangeable without comparing the actual section drawing.
One threshold at the selected length is supplied. Door sweeps, perimeter gasketing, optional fasteners and installation materials are not automatically included. Both existing length variants currently carry a 4 lb shipping-weight setting in Shopify; the actual packed weight of each length should be confirmed when quoting shipping.
