Dowel Plug
Definition and meaning of Dowel Plug in real estate.
A dowel plug is a short piece of a wooden dowel used to fill a counterbored hole and cover the head of a screw or fastener. This technique creates a clean, flush surface that hides hardware and enhances the visual appeal of wood finishes in custom cabinetry and flooring.
In more detail
To install a dowel plug, a carpenter drills a hole deep enough for the screw head to sit below the wood surface, inserts the screw, and then glues a matching plug into the remaining recess. Once the glue dries, the protruding portion of the plug is shaved flush with the surrounding wood and sanded smooth.
Plugs can be cut from the same wood species to blend in seamlessly, or from a contrasting wood type to create a decorative detail. This method is frequently used in high-end hardwood floor installations, custom built-ins, and wooden staircases.
