Expert Verdict — Reviewed by the SuperArbor Pro Desk
X panels suit shallow-slope layouts where a 1 in. drop per 4 ft. (roughly 1/4 in. per ft. average) is the design slope. Keep the thin edges continuous toward the low point so adjacent panels plane out without ridges. For crickets and steeper saddles, step up to the Y or C profiles in the same series.
Keep walk paths clear of loose panels and secure boards against wind uplift immediately after placement.
