How To Measure Radius
The radius of a bend is measured from the middle of the conduit, to the 90° point, not including the socket.
Below picture shows how the radius was worked out on 100mm, 90° bend.
- Stand bend against wall
- Measure from where wall meets floor to the underside of the conduit (in this example the measurement is 950mm)
- From this number, subtract the diameter of the socket (100mm)
- 950mm -100mm give a radius of 850mm.
