SturdiMount Mount Blocks are designed to provide a strong, smooth mounting surface that complements uneven exterior finishes such as lap siding, brick, stone or stucco. It’s a detail that is often overlooked that provides easy installation of light fixtures, vents, plugs, and more.

All SturdiMount Mount Blocks come preflashed to help manage water intrusion where exterior siding meets the block – so it performs as good as it looks.
