Multiple Concentric Termination Arrangements
The illustrations on this page show some of the installation arrangements for multiple concentric terminations that are allowed.
See Multiple Concentric Termination Clearances on page 30 for detailed information on clearances and additional arrangement options.
Note: When multiple concentric terminations are installed through a roof in the same location all termination caps must be at the same height measured from the ground.
Two Concentric Terminations
Two concentric terminations may be installed in close proximity as shown in Figure 37 or with standard clearances when this arrangement is not possible. See Figure 32 on page 30 for detailed information on clearances. See Figure 33 on page 30 when installing three concentric terminations.

Eight Concentric Terminations
Eight concentric terminations may be installed in two stacked groups of four, in close proximity, as shown in Figure 39. See Figure 36 on page 30 for detailed information on clearances.
Lateral groups of four as shown in Figure 35 on page 30 may be a more convenient installation arrangement for multiple groups depending on available space.
