Burner Wind Guard
Whether you need a replacement windguard for your existing burner or are building your own burner system, you need one of these. This is a stainless steel, 11.25" wide and 4" tall windguard and comes with a pre-drilled hole for attaching the burner to the frame and windguard.
Wind guards are designed to complement your burner as well as prevent the flame from blowing around excessively or blowing out altogether. Wind guards are also used to prevent loose items from getting too close to the flame. Burner wind guards will help contain rising heat from your burner, so that it's focused on the brew pot.
