Assembly

All seams to be caulked

Use one Roof Curb Assembly Kit with gasketing and hardware for each section to be joined. Attach self-adhering foam gasketing (supplied) to one side of either joining section (see Drawing 1a). Gasketing should be placed to form a continuous seal. Corner locations may need second strip to cover seam joints. Supplied hardware should then be used to secure the two sections together as shown (see Drawing 1b). Hold nut with wrench while bolt is tightened.

Drawing 1c shows two end panels and single center section. All sections and conﬁgurations are assembled in a similar manor.
