to annotations:
(1) Span
for loading = Straight section length
(2) Power = Steel armor,
600V, 4 conductor 750 kcmil; 3.8 Lbs. per
inch-width of tray
(3) CAT 5 = 4 UTP Category
5 (O.D. = .21, .026 Lbs./ft.)
(4) 200 Lb. Concentrated
Load - per foot affect per stated span
We = 2 x (concentrated Static Load) / span length
(5) w1 = Load to
calculate, kg/m (Lbs./ft.)
L12 = Span length in meters (ft)
squared
w2 = Tested Load, kg/m ( Lbs./ft.)
L22 = Tested span in meters (ft)
squared
(6) Loading is limited by rung
deflection, not failure. Span length is limited
to 1/3 section length for wall attachment.

| Note: The primary
and secondary lengths listed here are meant to direct
the user to lengths that best suit support span demands
and practical loading requirements. The primary
length is the one that is the most appropriate
for the strength of the system and that will provide
