Pemko 252X3DFG 72 Door Threshold Dark Bronze Anodized 72in

Product Description

The PEMKO 252X3DFG 72 is a door threshold designed for commercial and residential entryways where weather sealing and durability are priorities. It features an integrated ThermoSeal insert that reduces thermal transfer at the door base, helping to limit air infiltration at the sill line. The threshold is fabricated from aluminum with a dark bronze anodized finish, which resists corrosion and holds up in high-traffic door applications. At 1-1/2 inches tall, 5-1/8 inches wide, and 72 inches in length, it fits standard 72-inch door openings without field cutting. Door and hardware specialists or general contractors typically supply and install this component as part of a complete door assembly.

This threshold is suited for exterior door applications where a weather-resistant sill barrier is required. The ThermoSeal insert provides a compressible seal contact point against the door bottom, reducing drafts and moisture intrusion. The 72-inch length covers a standard double-door or wide single-door rough opening. The dark bronze anodized aluminum finish coordinates with common commercial storefront hardware and door frames, making it a practical choice for light commercial entryways, office buildings, and residential exterior doors requiring a clean, finished sill profile.

Key Features

• ThermoSeal insert reduces thermal transfer and air infiltration at the door sill
• Dark bronze anodized aluminum finish resists corrosion in exterior applications
• 72-inch length fits standard wide single or double door openings without additional cutting
• 1-1/2-inch height and 5-1/8-inch width provide a low-profile sill with broad coverage
• Anodized finish offers long-term color stability and surface hardness

Compatibility

Designed as an OEM-style replacement or new-installation threshold for standard 72-inch exterior door openings requiring a ThermoSeal insert sill with a dark bronze anodized aluminum finish.

Installation Notes

Installation is typically performed by a door hardware installer, carpenter, or general contractor. The existing door sill area should be cleaned and inspected for level before fastening the threshold. Fasten using appropriate masonry or wood screws depending on substrate, and verify the ThermoSeal insert contacts the door bottom evenly across the full width. Check local building codes for accessibility ramp requirements when the threshold height may affect ADA compliance at the entry.
