Mating Shielded Ducts to Risers

The new shielded ductwork is constructed so new cross-aisle troughs can be attached to risers of the former design. They fit outside of the older risers.

To attach the new shielded trough to a riser, first set it under the trough on the riser and install the other side of the trough as already described. Lift the trough as shown in Figure C-7, with the walls of the trough outside of the walls of the riser. Hold a nut under the trough, and bolt the parts together as shown.

Install Cross Aisle I/O Ductwork

1.If required, attach I/O endplate (group 6) to the cross-aisle brackets (group 10). See Figure C-8.

2.Install a cross-aisle bracket on both sides of the I/O trough where cross-aisle or wall trough is to be used. Place the bracket inside the I/O trough with its angle end outside. Secure the bracket using three thread-forming screws in each trough (use the holes in the bracket closest to the angle).

3.If cross-aisle, install brackets on I/O trough of cross-aisle cabinet.

4.Place I/O cross-aisle trough (group 10) or I/O wall trough (group 26) on brackets and secure with thread-forming screws.
