The scribe block is used to find the cabinet base on the blind side of a large overhang of the existing top. Slide the block onto a tape measure, bump the end of the tape against the blind side of the cabinet base that you want to template. Then push the block up to the edge of the overhang. Gently transfer that distance to the top and use 2 “L” targets at the end of the tape to shoot for an exact dimension to the base.
