The Big Horn 13516 Adjustable Siding Gauge Set supports one-person installation of 5/16-inch fiber cement lap siding by holding the next course at a consistent height while it is aligned and fastened. Each gauge adjusts from 4 to 8 inches in 1/4-inch increments to match a range of common siding reveals. Once set, the gauges carry the selected reveal from one course to the next, reducing repeated measuring, marking, and layout work. When used together, the two gauges provide balanced support for siding planks up to 12 feet long and help reduce the effort required to hold long boards in position. The locking clamp mechanism grips the previously installed course, while padded contact surfaces help protect primed or prefinished siding from scratches and marks. The two-point support system keeps the plank evenly positioned before nailing and leaves both hands available for final alignment and fastening. This 2-piece set is intended specifically for 5/16-inch fiber cement siding installation.
