Metal Vent Blocks for Block Fire Pits


Transform your backyard gatherings with the innovative Pine Tree Series Vent Blocks. Expertly crafted to enhance your retaining wall block-style fire pit, these metal vent blocks are not just functional; they’re a statement of style and a nod to nature (including the wood you burn). Thanks to the thoughtfully designed airflow system integrated into each piece, you can experience the magic of a smokeless fire ring. Pine Tree Series Vent Blocks are metal blocks you can put in place of Retaining Wall Blocks to give you the airflow to feed oxygen to the base of your fire. In order to make it smokeless, you will need a smokeless fire ring insert. Smokeless fire rings need to have an opening along the bottom row of blocks to vent the air from the outside to in between the blocks and the ring.
