Center Collar Details
The standard roof with a dome cap lid will have a center collar assembled from three (3) pieces. The dome
cap will mount onto it as well as the flashing. The dome cap is standard on all 12'-48' and 54' 40 Series
Bins. A flat top is standard on all 36'-60' 40 series bins.
For the 36'-48' dome cap bins, this will be the upper or “top” center collar. The lower or “Z” center collar
details are given on the later pages.
54' dome cap bins and 36' and larger flattop bins do not have the top center collar.
