A filler strip is a wood or plastic component that fills gaps or openings in woodworking. These strips can be fluted or beaded in design, and may even be reversible. Although standard sizes are available, many carpenters choose to create their own filler strips to match specific needs. It is crucial to use filler strips made from the same wood or material as the rest of the furniture or cabinetry to ensure a consistent appearance. Filler strips are compatible with nearly all wood types and finishes used in cabinets and are relatively simple to install. They can be secured using adhesives, nails, screws, or bolts. Filler strips can also function as chair rails in offices or as an alternative to molding along floors and ceilings.
