#Bearing Load may limit load

NR = Not Recommended

**Not recommended - KL/r exceeds 200

Notes

The beam capacities shown above include the weight of the strut beam. The beam weight must be subtracted from these capacities to arrive at the net beam capacity.
Allowable beam loads are based on a uniformly loaded, simply supported beam. For capacities of a beam loaded at mid span at a single point, multiply the beam capacity by 50% and deflection by 80%.
The above chart shows beam capacities for strut without holes. For strut with holes, multiply by the following:
- OS by 88%
- OS3 by 90%
- RS ( 9/16 holes ) by 88%
- RS3 ( 9/16 holes ) by 88%
- RS-MOD ( 3/4 holes ) by 85%
- RS-MOD2 ( 9/16 holes ) by 88%
- KO by 82%
