The term 'wood holder' can be broken down into two words, 'BIN' and 'cclamp'. A BIN is a container typically used for storage, usually made of plastic or metal. A cclamp is a type of clamp that is used to hold two pieces of wood together. It is usually made of metal and has two arms that are tightened with a screw. Together, these two items make up a wood holder, which is used to store and secure pieces of wood.
