Expert Verdict — Reviewed by the SuperArbor Pro Desk

Set the locking position to match your fiber cement panel thickness before nailing so the block sits flush with the siding face. Flash above the block and integrate it with the weather barrier to get the full water-management benefit. Match the block color to your siding brand's palette or coordinate with TopShield shutters and vents for a unified look.

Follow local electrical code when installing wiring behind any exterior mounting block or device.
