This extender addresses floor height variations and provides smooth transitions between different flooring materials. The mill finish aluminum construction resists corrosion and weathering in exterior applications.
Pemko manufactures this extender from anodized aluminum in their Ventura, California facility. The 2-inch width provides adequate coverage for most residential threshold applications. Mounting hardware is included for straightforward installation. This component works with Pemko door shoes and threshold systems to create weathertight seals.
