Fillers – Cabinet Glossary

What are Fillers?

Fillers are narrow strips of finished material used to close gaps between cabinets, walls, or appliances. They ensure proper fit, functionality, and a seamless finished look in cabinetry installations.

Quick Facts About Fillers

  • Widths: typically 3”, 6”, or custom sizes.
  • Lengths: typically 96" long and cut to size on the jobsite.  
  • Placement: between cabinets and walls, or to allow door clearance.
  • Finish: matched to cabinet style and color.

Use Cases

  • Closing gaps between cabinets and walls for a flush appearance.
  • Ensuring cabinet doors and drawers have room to open fully.
  • Customizing layouts when cabinet sizes don’t perfectly fit a space.

Designer Tip

Use fillers strategically near corners or walls to prevent doors from hitting obstructions and to maintain smooth functionality.  They can also be used horizontally to create a two piece crown molding.
