How to Bend Rigid Metal Conduit

Identify the conduit bender's take-up distance for the rigid metal conduit's bend angle, using the chart on the conduit bender's body. Find the desired bend angle on the chart and use the number associated with it. The take-up distance allows for the extra conduit needed to wrap around the conduit bender's arch.

Measure the distance between the fitting the rigid metal conduit connects to and the object the conduit bends around with a tape measure. Subtract the take-up distance from the conduit's distance measurement and transfer the total to a piece of rigid metal conduit. Make a pencil mark at the appropriate spot on the conduit.

Slip the rigid metal conduit into the conduit bender with the conduit bender's arrow on the pencil mark and the conduit bender's shoe facing the bend. The arrow points to one end of the conduit bender's arch and the shoe mounts on top of the other end of the arch.

Place a foot on the conduit bender's shoe and grip the bender's handle with a hand. Apply pressure to the shoe and handle. Roll the conduit bender across the rigid metal conduit until the correct conduit-bender degree mark reaches the straight section of conduit.

Remove the bent rigid metal conduit from the conduit bender. Check the conduit's bend against the corner or obstruction. Form all additional bends using the same method.
