The Beam Cutter by Timber Tuff perfectly guides your chainsaw to give you straight and even beams, board after board. The bar length is universal and quickly and easily attaches to any chainsaw. The blade clamp is .5" wide by 2" deep, while the cutter measures 12" x 7.5" x 2.5" overall. The sizing makes it convenient to take with you anywhere. Take the cutter to the log, not the log to the cutter for ease of use. It's constructed of solid steel with a powder-coat finish for corrosion resist, so it lasts you the long haul. I.
