Center Collar Placement
The following figure gives the approximate height needed to install the center collar.
With two sidewall rings in place, position the center collar at the height specified, measuring from the
bottom of the center collar to the foundation as shown. If additional rings are required for construction pur-
poses, add 32 in. for each additional ring.
NOTE: It is better to set the center collar a little too high. Do not set the center collar too low.
