Now all the dogs can play!  The B.O.S.S.  Hybrid is designed for heavier usage. It has an all wood frame also however the boards are cut down to 3" x 1 3/8" for a more precise fit and are sanded smooth and ready for stain or paint.  All of the cross members and gussets are made of composite plastic instead of plywood. The belt is our heavy duty composite belt. ( Same as on our Pro Series mills) This makes for a very stable slat mill that is smooth and quite.    It is available as a kit or fully assembled and in both medium and large sizes.
