I was under the impression that clamps were not neccessary for single gang plastic boxes. I did read somwhere that they are required for anything larger than a single box.

I was unaware they even made a clamp for a plastic box. I thought as long as you stapled within 6" from the box you were OK.

Let me know what you think...

You are correct (as far as the NEC goes at least). Anything larger than a singlegang needs to have clamps. Mr. Electric

Question on those clamps for double gang boxes and larger...

Are the clamps already attached? I noticed when installing the double boxes that the knockouts are different than the singles. It looks as if they are to stay attached to the box and kind of support the wire.

Or, do you knockout those clamps and purchase some type of clamp? Although I have never seen a clamp for a plastic box when I shopped for electrical supplies?

Thanks for the help.

All the multi-gang placstic boxes I've seen have a built in clamping device.
