Heavy Duty 3/16" wall dual 3x6 beams make up this sturdy frame. Center sections are welded every two feet apart to give you the most rigid frame to handle un-level ground set-ups, and the abuse of loading heavy logs onto the frame.
Thin wall frames, and single rail frames don't hold a candle to the strength of this twin beam system.
Accu-Trac sawmills gives the most stable and accurate cut available.
