    Suspending Conduit vertically for camera pendants

    Hello,
    I need some help with what the code says for suspending a camera 18' from a beam with Rigid Conduit. I am attaching my mock-up camera mount but keep in mind the camera will have to suspend 18' down from the beam. I was planning on using the Edge type conduit beam clamp. Please advise.

    I would recommend a swivel plate like this.

    The world is round, you will get there no matter what path you take.

    Agree on the swivel plate, particularly if forklifts are in use. Won't eliminate forklift damage but will certainly reduce it.

    How does that help? The OP said that the cameras MUST hang down 18 feet. What does putting that swivel on the JB at the end of 18 feet of rigid buy you?

    Without the swivel, something has to bend, break or otherwise move out of position. With the swivel, it's often just the camera that gets trashed; a quicker repair. At least that was my experience.

    It buys you a flex point - 18' feet and a little touch by something and SNAP!
    Other than just hanging by chain or cable I think it is a much better deal . I'd check the max weight of the swivel though. Probably use AL conduit

    I think the proposal is to put the swivel at the top end of the 18' of rigid, not the bottom end. The bottom end would buy you a very small amount of displacement; the top end buys you a lot.

    Cheers, Wayne

    Thanks, that is what I was suggesting also.

    Ditto. This thread was great. I didn't know those existed.

    All cameras will be hanging above conveyor belts so nothing will have the ability to hit the pipe. I didn't want to use the swivel plate because that means I will have to re-thread 100 pieces that I cut to length. Has anyone here used the clamp I posted a picture of. Thanks
