<p>The Isokern Brick Ledge<br />component is uniquely<br />designed to allow a<br />brick or stone chimney<br />to exit out through the<br />roof for interior fireplace<br />installations. This<br />component eliminates<br />the cost of having excess<br />masonry carried down to<br />the footer, a major cost<br />saver to the consumer.</p>
