For siding installation, similar to SA902, but this newer model will not scratch pre-painted siding. Heavy-gauge plastic helps avoid marring the painted surface. One person can install fiber cement siding while ensuring each course stays level. Adjusts in 1/4" increments for a 4"- 8" plus 8 1/2" reveal. Sold in a set of two. Can be used with 5/16 hardi-board.
