The typical radius is 24 inches. Fittings are also available for 30°, 45°, 60° and 90° angles. It may be necessary to add supports to the tray at these points. Refer to CSA/NEMA VE2 installation guidelines for suggested support. Calculate cable tray offset dimensions, bend section length, and horizontal run for obstacle routing Two Bends Per Offset: Every offset requires two equal bends — one to move laterally and one to return to parallel. Pre-fab vs Field Bent:. Compute precise cable tray offset geometry, run lengths, and diagonal travel dimensions for tray routing elevation changes. Calculate true diagonal travel lengths, horizontal runs, and bend geometry for ladder.

Measure this distance along the straight tray. This publication is intended as a practical guide for the proper and safe* installation of cable ladder systems, cable tray systems, channel support systems and associated supports.
