Rubberwood * Product shown unfinished * 3.5 in. L x 3.5 in. W x 35.5 in. H Hardware Resources is proud to present the du Bois Collection of moulding and domestic wood products. Each piece of du Bois moulding is kiln dried until it contains only 6-8% moisture, ensuring that the moulding will not swell, shrink or split when installed. Each piece is hand-fed into the saws and monitored closely as each unique profile is cut into the wood.
