Rustic Double Pipe Blocks

Rustic Double Pipe Blocks provide a professional, weatherproof solution for sealing dual pipe penetrations through exterior siding, particularly fiber cement. Engineered specifically for natural gas furnace intake and exhaust pipes, these blocks create a secure, airtight mount (when caulked accordingly)
that prevents water infiltration and air leakage around pipe entries. The rustic finish integrates seamlessly with siding while maintaining structural integrity and energy efficiency at critical building envelope points.
