These butcher block countertops are made in the USA by John Boos & Co. – a leader in the food service industry. These tops are NSF-certified, so approved for use in commercial establishments if you select Natural Oil as your finish. They feature Hard Rock Maple, which is the hardest and most durable North American hardwood. They are constructed in blended-grain style. Blended-style butcher blocks are made using wood pieces of varying length to create the interior rails of the block, whereas the outermost rails feature wood strips that run the full length of the block. These particular counter tops are 1-1/2 inches thick, 36 inches wide, and 132 inches length. Finish options include food-safe natural oil (for tops you will cut upon) and Varnique (a low-maintenance varnish-like coating not intended to be cut upon). MPL SCT 132X36X1-1/2 OIL
