Pemko 255A73 Saddle Threshold Mill Finish Aluminum

Product Description

The PEMKO 255A73 is a saddle threshold manufactured from aluminum with a mill finish. It spans 73 inches in length, 5 inches in width, and 0.5 inches in height, making it well suited for standard and wide commercial or residential door openings. Saddle thresholds bridge the gap between door and floor, providing a smooth transition surface while sealing against air, water, dust, and pests at the base of the door. This threshold is a direct architectural door hardware component installed by finish carpenters, door and hardware technicians, or general contractors during new construction or door renovation work.

The 255A73 is intended for use at exterior or interior door openings requiring a low-profile saddle-style threshold. Its 73-inch length accommodates single and some double door configurations without field cutting in many standard applications. The mill finish aluminum construction suits installations where the threshold will be painted or where a natural aluminum appearance is acceptable. It is commonly specified on commercial, institutional, and residential projects requiring a durable, code-appropriate transition at the door sill.

Key Features

• Saddle threshold profile provides a smooth, low-profile transition between door and floor surface
• Mill finish aluminum construction resists corrosion and supports field painting or anodizing
• 73-inch length fits standard and some oversized single door openings
• 5-inch width provides stable bearing surface across the door sill
• 0.5-inch height keeps the threshold ADA-compliant with low-rise beveled transition
• Sold as a single unit for straightforward ordering and installation

Compatibility

Designed as an OEM-style replacement or new-installation saddle threshold for standard commercial and residential door frames requiring a 73-inch aluminum sill transition.

Installation Notes

Installation is typically performed by finish carpenters or door hardware technicians using standard drilling and fastening tools. The threshold should be secured to the subfloor or sill using appropriate fasteners for the substrate material; ensure the door is closed and the opening is measured accurately before cutting or drilling. Follow applicable local building codes and ADA guidelines for threshold height and transition slope at accessible entrances. Remove any existing threshold hardware and clean the sill surface thoroughly before setting the new threshold.
