Therefore, Mounts can be placed up to (4) rafters apart in landscape, and up to (2) rafters apart
in portrait (16” x 2 = 32” < 37”).
*Note: only a single piece of Trim is called out for this array. A piece of Trim could be cut to
length on-site to cover the stagger, as shown below, but is not necessary. The designer will
have to make an aesthetic/economic decision, whether to include such partial pieces.
