System and method for placing a conduit hole in an enclosure

A kit for measuring a center point for a knockout of an enclosure, comprising:

• a set of threaded caps, each threaded cap having a corresponding size and a threaded interior wall that allows for threaded attachment of the threaded cap to one of a plurality of conduits having a standard diameter size, each of the plurality of conduits intended for extension into an enclosure through a corresponding knockout formed in the enclosure, each threaded cap comprising a marking element disposed at a center point of the threaded cap, the marking element configured to allow for measurement of distances from the center point of the threaded cap to an adjacent outer side edge of the enclosure and from the center point of the threaded cap to an adjacent outer front or back edge of the enclosure to thereby mark a center point of the corresponding knockout to be formed;
• and
• a centering square comprising open grooves that intersect at a crossing point, the centering square configured for placement on the enclosure with the crossing point aligned with the marked center point to allow for formation of crossed lines using the open grooves that intersect at the center point of the corresponding knockout to be formed and which can be aligned with center marks on a knockout die of a knockout punch.
