Molding & Trim

Filler Strip

Also known as: Cabinet Filler, Filler

A narrow piece of finished material (typically ¾ inch thick and 3 to 6 inches wide) used to fill the space between a cabinet and a wall, an appliance, or another cabinet. Filler strips ensure doors and drawers can open freely without hitting adjacent surfaces and provide a polished transition. They are essential in corner configurations and appliance alcoves.

In practice

Fillers absorb the difference between standard cabinet widths and real wall dimensions, and keep doors and drawers clear of walls and appliances. Typical widths are 3" and 6", trimmed on site.
