The bottom duct work is rotated into place as shown. The bottom ductwork is a tight fit by design.
The upper part of the duct fits under the bottom duct adapter and requires a tight fit which with
the gasket material maintains the IP 54 and UL and NEMA 12 rating.

The cutout is made on the innermost gland
