3.Lower the support box through the hole in the roof until the bottom of the box extends at least 2" below the ceiling (see Figure 24). Align the support box vertically and horizontally using a level. Temporarily tack the support box in place through the inside walls and into the roof sheathing.

4.Using tin snips, cut the support box from the top corners down to the roofline and fold the resulting flaps over the roof sheathing (see Figure 25). Apply a bead of non-hardening mastic around the top edges of the support box to make a seal between the box and the roof. Nail in place with roofing nails. Remove any combustible material that might be in- side of the support box.

5.Complete the cathedral ceiling instal- lation by following the same proce- dures outlined in steps 2 through 7 for Flat Ceiling Installation, page 12.
