Pemko EXT2D36 Threshold Sill Extender 36 in Dark Bronze

Product Description

The PEMKO EXT2D36 is a threshold sill extender designed to widen the bearing surface of residential door sills where standard sill width falls short of the rough opening or flooring transition. At 36 inches in length and 2 inches in nominal width, this extender attaches to compatible Pemko residential sill profiles to close gaps at the door base and provide a continuous, flush transition surface. The dark bronze anodized aluminum finish delivers corrosion resistance suited to both interior and exterior threshold applications. Installation is handled by a door hardware technician or finish carpenter working on entry door assemblies.

This extender is used in residential entry door installations where the existing sill does not span the full width of the opening or where a flooring change requires a wider threshold footprint. Typical scenarios include new construction rough openings, remodel door replacements, and accessibility upgrades where a broader, low-profile sill transition is required. The anodized dark bronze finish coordinates with common commercial and residential door hardware finishes.

Installation Notes

This product is typically installed by a door hardware technician, finish carpenter, or experienced installer working on entry door threshold assemblies. Secure all door panels and ensure the door is held open or removed before working at the sill. Fasten the extender per the sill manufacturer instructions using appropriate fasteners for the substrate material. Consult local building codes for threshold height and ADA accessibility requirements where applicable.
