work as shown to the right. Use the inside of

closure for the opening.

the cut-out on the gland.
The cut-out is made on the innermost gland
plate. The remaining two gland plates must be

duct assembly.
3.55: Enclosure bottom cut-out
3.56: Bottom duct work installed
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.
