Expert Verdict — Reviewed by the SuperArbor Pro Desk
Set both gauges to the same reveal before you start and re-check after the first course, since a quarter-inch drift compounds over a whole wall. Keep a spare set on larger crews because they pay for themselves in layout time on the first day. They are sized for 5/16 in. boards, so confirm your board thickness before ordering if you are running a different product line.
Boards must still be fastened per the siding manufacturer's nailing pattern; never leave boards supported only on the gauges, and follow ladder and scaffold safety when working at height.
Order the Pactool Gecko Gauge SA903 and hang fiber cement siding solo with fast, accurate reveals.
