Special angle elbows
Special angle elbows are traditional elbows that allow the direction
of the busway runs to change at angles greater than 90°. They allow
easy routing through non-traditional corridors. The four types offered
are forward, rearward, upward, and downward. See minimum leg
lengths for each type listed in Table 23 and Table 24.
