How to Measure Your Chimney Cap
Fill in the blanks of the
diagram below to determine your chimney cap size and provide
measurements for ordering. If you have a chimney with a clay

chimney requires a cap that is the full length and or width of
the chimney plus the amount it is out of square. The reason is
that an out of square chimney is skewed. Thus, if your chimney
is 1/2" out of square and the opposing sides on the out of
square dimension are 36", you will need a 36 1/2"
chimney cap on that dimension to compensate for the out of
square. (See diagram below.)
size of your spark arrestor. The Classic Bell has a standard
24" inside height for the spark arrestor; the Suburban a
20" height. This is more than sufficient for most chimneys,
but be certain: measure your spark arrestor height!
