Solid Chimney Block
$36.58Chimney blocks are one-piece interlocking components that make it easy to add an all-masonry chimney to your indoor or outdoor fireplace. These nesting chimney blocks can be stacked as high as building code allows, and have been independently tested at a compressive strength of 3,000 PSI. To further increase the strength of our chimneys, rebar and mortar can be placed into the “hurricane” holes.
