Chemical Resistant Brick: Chimney Liner Brick Shapes

Chimney Liner Brick Shapes


Note: Total Chamfer (Ct) equals 2 x Ct is available in 1/16" increments only. Dimension lines designated as 'C' can be custom manufactured to the size specified by the designer for any chimney liner diameter desired. Dimension lines designated as 'L' can be custom manufactured to the size required up to and including 8"
