The extra wide starter block is a key component for gas flue systems, offering a robust foundation at the base of masonry chimneys or flue liners. Manufactured for strength, it suits installation environments where durability is important.
On site, this starter block is commonly positioned at the beginning of flue construction or repair. Its wider format aids in achieving stable, level alignment when assembling larger or heavier flue assemblies, tailored to residential or light commercial chimney work.
