Pemko 171D 72 Door Threshold Dark Bronze Anodized Aluminum

Product Description

The PEMKO 171D 72 is a door threshold designed for installation at the base of exterior or interior door openings to seal the gap between the door bottom and the floor surface. Measuring 1/2 inch in height, 5 inches in width, and 72 inches in length, this threshold is fabricated from aluminum with a dark bronze anodized finish. The anodized surface provides corrosion resistance and a clean appearance suited for commercial and residential door frames. Installation is typically handled by carpenters, general contractors, or door hardware specialists.

This threshold is commonly used in commercial entryways, institutional buildings, and residential door openings requiring a low-profile transition between floor surfaces. The 72-inch length accommodates standard and wide door openings without requiring a cut-down on most single-door applications. The 5-inch width provides a broad bearing surface across the door sill.

Key Features

• Low-profile 1/2-inch height minimizes trip hazard at the threshold crossing
• 5-inch width provides full sill coverage across standard door openings
• 72-inch length fits standard single and wide door applications
• Dark bronze anodized finish resists corrosion and wear
• Aluminum construction keeps weight low while maintaining structural rigidity

Compatibility

Designed as an OEM-style replacement or new-installation threshold for standard commercial and residential door frames accepting a 5-inch wide sill threshold profile.

Installation Notes

Installation is typically performed by a carpenter or door hardware technician using standard drill and screw hardware appropriate for the sill substrate. The threshold should be set with the door in place to confirm clearance between the door bottom and the threshold surface before fastening. Verify local building codes for ADA-compliant threshold height requirements, as the 1/2-inch rise may require a beveled transition in accessible routes. Power tools and sealant are commonly used to complete the installation.
