This model is not currently offered as a verified ready to buy print.
What it does
- Sized for 6mm drilled holes so it matches pegs in cabinets and shelves
- Round cap shape covers open dowel holes for a cleaner look on wood surfaces
- Doubles as a cosmetic end cap for pipes and tubes near the same size
- Simple shape blends into cabinets, shelving units, and workshop projects
- Compact size fits into kitchen cabinets, closets, and other tight spots
Under kitchen cabinets and inside closets, drilled dowel holes often sit open and exposed. This cover cap is shaped to sit inside a 6mm hole, giving cabinets, shelves, and woodworking pieces a neater, finished look.
The cap has a round, simple form sized for 6mm pre-drilled holes, the kind used in many cabinet and shelf systems. You can use it to cover peg holes in particle board furniture, or set it into other 6mm holes around your home workshop.
Beyond cabinets and shelves, this cap also works as a cosmetic end cap for pipes and tubes close to the same diameter. It gives you a small, tidy way to finish off an open hole wherever one shows.
