1 Minimum safety factor, Ω, for tabulated values is 2.5.
2 No reductions to tabulated loads need to be applied for bracket attachment to strut. The published load values are for the brackets mounted on the channels,
away from the channel edges
3 For bracket attachment to 14 gage( e. g. MT-40) vertical channel, multiply tabulated load values by 0.61. The published load values are for the brackets mounted
on the channels, away from the channel edges
4 For bracket attachment to 12 gage( e. g. MT-50) vertical channel, multiply tabulated load values by 0.66. The published load values are for the brackets mounted
on the channels, away from the channel edges
5 The loads apply only when strut profile opening is facing upward or downward.
6 The bracket’ s self-weight has been accounted for in the table load values.
7 Load values are for bracket only. Design professional is responsible for checking base material and fastener strength.
