Cable Tray Fitting Radius Selection Table
Cable Tray Fitting Radius Selection Table reference with assumptions and boundary notes.
Reference boundary
Cable tray fitting reference only. Cable bend limits, tray series, fitting catalogue data, and installation conditions govern actual radius selection.
Reference table
Compare common cable tray fitting radius labels and cable outside-diameter multiplier references.
| Fitting type | Typical radius reference | Example at 30 mm cable OD (mm) | Boundary |
|---|---|---|---|
| Horizontal elbow | 9x cable OD | 270 | radius reference only; cable bend limit and tray fitting catalogue govern actual selection |
| Vertical inside elbow | 12x cable OD | 360 | radius reference only; cable bend limit and tray fitting catalogue govern actual selection |
| Vertical outside elbow | 12x cable OD | 360 | radius reference only; cable bend limit and tray fitting catalogue govern actual selection |
| Horizontal tee | 9x cable OD | 270 | radius reference only; cable bend limit and tray fitting catalogue govern actual selection |
| Horizontal cross | 9x cable OD | 270 | radius reference only; cable bend limit and tray fitting catalogue govern actual selection |

- Use this table for preliminary reference and arithmetic checks only.
- Confirm equipment ratings, product markings, installation conditions, utility requirements, and the local authority requirements before design or field use.
