The Boss Mate corner tool is crafted from sustainably sourced hardwood and designed as a former for shaping corners in lead bays. It matches the height of a wood roll and features a precise 90° angle. The ergonomically placed handle allows users to apply pressure effectively into the corner and sole of the bay. This design enables users to work against the sides, ensuring square corners and the correct height for fitting a roll. Additionally, it can be turned on its side for greater height when needed. I’ve also introduced a 45° Boss Mate for use on bay roofs and hips.
