Description

The PEMKO EXT2A36 is a sill extender designed for use with residential door threshold sills. Finished in mill finish aluminum, this extender adds surface area to existing sill assemblies where additional coverage or transition support is needed at the door opening. It measures 36.5 inches in length, 2.5 inches in width, and 1 inch in height, and ships as a single unit weighing 0.73 pounds. Installers working on door threshold systems will find this a straightforward add-on component for extending sill reach without requiring a full threshold replacement.

This extender is suited for residential door applications where the existing sill needs additional width or length coverage. Typical scenarios include new construction door rough openings, renovation projects where flooring transitions change the sill geometry, or replacements where the original extender has been damaged. The mill finish aluminum construction provides corrosion resistance appropriate for interior and protected exterior threshold assemblies.
