10. Center Collar Details

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 18'-36'
40 series bins. A flat top is standard on all 42'-60' 40 series bins.

For the 36' 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.

36' and larger flattop bins do not have the top center collar.
