    I just bought a bag of 5 of these at my local Home Depot. Part# 20512. 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!

            Learn how to size connectors
            All the reviews saying that it is 7/8 not 3/4 are not aware how connectors are sized.The OUTSIDE diameter of the connector is 7/8.The INSIDE diameter of the connector is 3/4.When drilling a hole for a 3/4 connector,you drill a 7/8 hole. Martins Electrical
