Pemko 145D72 Interlocking Threshold 72 in Dark Bronze Aluminum

Product Description

The PEMKO 145D72 is a 72-inch interlocking threshold designed for commercial and architectural door applications. Finished in dark bronze anodized aluminum, it provides a durable, corrosion-resistant barrier at the base of a door assembly, sealing the gap between the door bottom and the floor. The interlocking profile mates with a compatible door bottom sweep to create a weather-tight seal that resists air infiltration, dust, and moisture. At 4 inches wide and 7/8 inch in height, it fits standard door frame openings without requiring extensive floor modification. Licensed contractors and commercial door installers specify this threshold for new construction and replacement projects where both performance and finish aesthetics are required.

The 145D72 is suited for commercial and institutional entryways where door weathersealing, traffic durability, and a clean architectural finish are priorities. The dark bronze anodized finish complements standard commercial door hardware finishes common in office buildings, schools, healthcare facilities, and government installations. It is sold as a single 72-inch length, which covers a standard 6-foot door opening. Installers working on double-door assemblies or custom-width openings should verify the rough opening width before ordering.

Key Features

• Interlocking profile mates with compatible door bottom sweeps for a weather-resistant seal
• Dark bronze anodized aluminum finish resists corrosion and matches standard commercial hardware
• 72-inch length covers standard 6-foot door openings without field cutting in most applications
• 4-inch width provides stable bearing surface across the door threshold zone
• Anodized aluminum construction resists wear from high foot traffic

Compatibility

Designed as an OEM-style interlocking threshold for standard commercial door assemblies requiring a door bottom sweep counterpart. No specific compatible model numbers were provided in the product data; verify sweep-to-threshold profile compatibility before installation.

Installation Notes

Installation is typically performed by a licensed door hardware technician or commercial contractor. The threshold is fastened to the floor substrate using appropriate anchors for the floor material; ensure the subfloor is level before securing to avoid gaps in the interlocking seal. Power tools may be used to cut the threshold to finished width if the rough opening is less than 72 inches — use a fine-tooth blade appropriate for aluminum. Verify compliance with local building codes and ADA threshold height requirements before finalizing installation height.
