## Abstract

A lap siding product with a central face cut or medial groove, allowing an installer or user to break the lap siding product in half manually, without tools, resulting in two pieces of lap siding. The central face cut or groove extends for the length of the product, and its depth is a substantial portion of the thickness of the lap siding product. A central back cut or medial groove opposite to the central face cut or groove may be provided, as well as a pair of back spacing cuts or rabbets along the edges of the back face of the product. A pair of machined nail lines on the face of the product assist in determining locations for nailing the post-break pieces of lap siding during installation.
