What We Like About This Fireplace Mantel This fireplace mantel is a generously cut piece of basswood with rough bark front smooth top and smooth sides. The bark of the front of this mantel has a natural surface with the irregular rough surface of hea rty North American trees.Please note: Mantel shelf will vary slightly from the one shown. Because each log is different each mantel has its own unique grain and characteristics. These differences do not affect the structural strength of the mantel.Di mensions: 60L x 10D x 4H inche
