These work exactly as described... clearly the people commenting that they are not the correct size, do not know how electrical conduit sizing is labeled. The size on the package is the interior diameter (I.D.) of the fitting,,, not what size knock out it fits in.

I am doing an electrical project and the knockout on the junction box is 3/4". These connectors are actually 7/8" and do not fit. The bag says 3/4", but don't fall for it!

They are labelled 3/4 inch but that is a lie - they are over in inch in both interior and exterior and therefore do not fit my 7/8" box (HD does not carry 7/8", but if they did presumably they'd be even larger!) Buyer Beware.
