Pemko 173A72 Saddle Threshold Mill Finish Aluminum

Product Description

The PEMKO 173A72 is a saddle-style door threshold manufactured from mill finish aluminum. It spans 72 inches in length, measures 2.25 inches wide, and stands 0.1875 inches high — a low-profile profile that accommodates foot traffic and rolling equipment without creating a significant trip hazard. This threshold seals the gap at the base of a door opening, reducing air infiltration and providing a finished transition between floor surfaces. It is installed by commercial door and hardware contractors, general contractors, and facilities maintenance technicians on standard door openings requiring an ANSI/BHMA A156.21-compliant threshold solution.

The 173A72 is suited for commercial and light industrial door openings where a flat, saddle-style threshold is specified. Its 72-inch length fits standard double-door openings or can be field-cut to fit single-door frames. The mill finish aluminum construction makes it appropriate for interior applications and covered exterior entries where anodized or painted finishes are not required by spec. Typical installations include office buildings, warehouses, schools, and retail facilities.

Key Features

• Saddle-style profile provides a low 0.1875-inch rise, reducing trip hazard at the threshold
• Mill finish aluminum construction resists corrosion and is field-cuttable to required width
• 72-inch length accommodates standard double-door openings or can be trimmed for single-door use
• Meets ANSI/BHMA A156.21 standards for threshold performance
• 2.25-inch width provides full coverage at typical door-frame bottom gaps

Compatibility

Designed as an OEM-style saddle threshold for standard commercial door openings requiring an ANSI/BHMA A156.21-compliant aluminum threshold in mill finish.

Installation Notes

Installation is typically performed by a licensed door hardware contractor or general contractor. The threshold is surface-mounted to the floor using appropriate fasteners for the substrate — concrete anchors for masonry floors, screws for wood substrates. Field-cutting to length should be done with a fine-tooth metal blade to maintain a clean edge. Ensure the door bottom clearance is correct before fastening to avoid binding against the door sweep or shoe.
