Product Details

Description

This 4-inch B-Vent Firestop Spacer is an essential safety component for gas appliance venting systems. Designed to maintain the necessary clearance between Type B gas vent pipes and combustible materials, it ensures a secure and code-compliant installation as the vent passes through floors or ceilings. By centering the vent pipe and acting as a fire-rated barrier, this spacer helps prevent the spread of fire and smoke through floor openings. It is a critical part for any HVAC project involving gas furnaces, water heaters, or boilers requiring a 4-inch exhaust system. Constructed from durable, heat-resistant metal, this firestop spacer provides long-lasting reliability and structural integrity for your venting stack.
