Filler Strip
A filler strip is a flat, finished piece of material, typically about 3/4 inch thick and 3 to 6 inches wide, installed between a cabinet and a wall, an appliance or another cabinet. It closes a planned gap and lets the run of cabinets finish cleanly.
Why are fillers needed? Stock cabinets come in set widths, but rooms don’t. If a wall is a couple of inches longer than the run of cabinets, there’s no cabinet that fills the space. A filler takes up the difference. Fillers are also used in corners so doors and drawers can open without hitting each other or the handle next to them, and they let you keep clearance beside a fridge or range.
In custom cabinetry, cabinets can be built to the exact size of the room, so a filler is used where it makes sense rather than to hide a mismatch. Fillers are made of the same material and finish as the doors so they blend in, and they are often scribed to follow an uneven wall.
Fillers differ from scribe moulding. Fillers close larger gaps (inches) and are part of the cabinet run. Scribe moulding is thin trim that covers small gaps (fractions of an inch) along the edges.
