Pemko 177AV 72 Threshold Vinyl Insert Mill Aluminum

Product Description

The PEMKO 177AV 72 is an aluminum door threshold with a vinyl insert, designed to seal the gap at the base of an exterior or interior door. The mill aluminum finish provides a clean, uncoated appearance suitable for a wide range of commercial and residential door applications. At 72 inches in length, this threshold fits standard double-door openings and many wide single-door frames. The vinyl insert compresses against the door bottom to reduce air infiltration and provide a basic weatherseal. Door installers, glaziers, and general contractors are the typical trades that source and install this component.

This threshold is used in commercial and residential construction where a finished, functional sill barrier is required at the door base. It is suited for new installation or retrofit work on wood, hollow metal, or aluminum door frames. The 72-inch length allows field cutting to fit narrower openings. Mill finish aluminum is compatible with a variety of finish treatments if field painting or anodizing is required after installation.

Key Features

Compatibility

Designed as an OEM-style replacement or new-installation threshold for standard commercial and residential door frames requiring a 72-inch aluminum sill with a vinyl weatherseal insert.

Installation Notes

Installation is typically performed by a door hardware installer, glazier, or general contractor. Secure the threshold to the floor substrate using appropriate fasteners for the substrate material. Ensure the door bottom clearance is set correctly so the vinyl insert makes consistent contact without binding door operation. Follow applicable local building codes for accessibility and weatherproofing requirements at door sills.
