Carpentry rod is a term used to describe a cylindrical piece of wood, usually made from hardwood, that is used in carpentry and joinery. The most common type of carpentry rod is the DOWEL, which is a round wooden rod with a uniform diameter and length. Dowels are used to join two pieces of wood together, as well as to reinforce joints and provide additional support. They can also be used to create decorative elements in furniture and other woodworking projects.
