Conduit should be supported within 3 ft. of a box, with additional attachments no more than 10 ft. apart. One method is to clamp the conduit tight to the wall with single-hole conduit straps. But if you do this, you'll have to either bend an offset in the conduit or use an offset fitting where the conduit enters boxes. You can avoid offsets by attaching the conduit with conduit hangers. These hangers hold the conduit off the wall so it can run straight into boxes with no offset.
To install conduit hangers, hold the conduit against the wall where you want it and make a mark on the top and bottom where the hanger will go. Remove the conduit, center the strap between the marks and attach it with a screw. It's best to locate the hangers over framing for a solid attachment, but if you can't, use a drywall anchor instead. Now simply slip the conduit into the hanger and secure it with the included bolt and nut.
