One-Man Solo Operation: Acts as a reliable second set of hands, allowing a single installer to accurately lay out and nail heavy, full-length 12-foot fiber cement boards.

James Hardie Optimized: Engineered explicitly to fit 5/16" thick fiber-cement siding planks, delivering flawless compatibility with standard James Hardie lap profiles.

4" to 8" Adjustable Reveals: Adjusts smoothly in precise 1/4-inch increments to lock in consistent lap exposures anywhere from 4 inches up to 8 inches.

Friction-Cam Grip: Features a patented heavy-duty Friction-Cam locking mechanism that bites tightly to the lower board to support the deadweight of the next course without slipping.

Non-Marring Material: Constructed from high-strength, heavy-gauge compound plastic that will not scratch, scuff, or mar pre-painted or primed siding finishes.
