B-Line Eaton series imperial cable tray and ladder, 4" Height, 17.598" Length, 24" Width, Series 2-5 vertical outside bend, Aluminum, 30° Angle, 24" R

Both change elevation, but they turn opposite ways relative to the tray bottom. An outside bend, which is what model 4A-24-30VO24 is, bends away from the cable side, so it is what you use when the run rises up over a beam or duct and the cables ride the outside of the curve. An inside bend turns toward the cable side, used coming back down or dropping under an obstruction. Order them in pairs when you go over and back down, and match the angle, 30 degrees here, on both.

Allow 17.598 inches of length for the fitting itself. That is the dimension to subtract from your straight-section takeoff when you lay out the run, along with the 24 inch bend radius that sets how far the tray swings through the 30 degree turn. Work it into the drawing before you cut straights to length.

The fitting is aluminum, which is the usual choice over steel where moisture, washdown, or mildly corrosive atmospheres are a concern, and it keeps the weight down for overhead support. At 6.062 lb for the fitting, a single installer can set it on the hangers without a lift.

Yes. The 4A-24-30VO24 vertical outside bend carries CSA certification, which is what an inspector on a Canadian project will look for on the tray system.

The 4A-24-30VO24 is supplied as the bend fitting itself. Splice connectors, hardware, and any supports at the elevation change are separate items, so add them to the order and plan a hanger near each end of the fitting as required by your support layout.
