Traditional strut solution
Using traditional strut channels, the maximum support uniform load capacity at 48" long would be 851 lbs. with .224" of allowable deflection. Using traditional strut would not work with these parameters; so spacing would need to be reduced to 6' 6" to accommodate the load. To avoid the reduced spacing, the contractor would need to change the configuration to back-to-back traditional strut channel. This would double the cost of the solution, may increase lead-time, and could significantly increase the overall installation cost.
Eaton’s B-Line series 4Dimension strut solution
By using Eaton’s B-Line series 4Dimension strut (4D22), the contractor can elect to utilize the multi-sided functionality and mount pipe over and under the channel. This will result in a 24" long strut channel versus the traditional 48" long strut channel; thus, reducing the material cost up to 55%. If compared to welded back to back 1-5/8" channel, 4D22 also reduces the vertical space taken by 1-1/8". This 24" long 4D22 strut channel has the load capacity of 1,872 lbs. with .10" of deflection; therefore, allowing the distance between supports to be the planned 10'.
A huge benefit is the ability to work on the entire trapeze from one location because the trapeze is half as long. This saves the installer trips up and down ladders or adjusting lift locations. The installer may even reduce rental costs by reducing the number of man lifts required to perform the work.
4Dimension cuts up to 10 x’s faster due to material thickness, which can also reduce cost of cutting materials (ie.: saw blades).
