Keep walls safe from hot, wood or coal stoves, with this Wall Spacing Kit. These pre-drilled ceramic spacers create an insulated air space between heat shields and walls. Walls insulated by this air space are protected from nearby hot stoves. Used to safely reduce minimum wall and ceiling clearances between the heat shield and the wood stove. This kit includes 10 - 1" ceramic spacers, 10 - 2 1/2 " black oxide screws, 10 wall anchors (will need 1/4" hole drilled), and mounting instructions.
