Abstract
A connector adapted to secure an electrical power line entering an electrical meter box comprises (a) a cylindrical member adapted to be at least partially inserted into the meter box through an access hole, (b) a flange affixed to or integral with a first end of the cylindrical member and (c) a cylindrical grommet selectively insertable at least partially into a second end of the cylindrical member and securable therein. The flange remains outside of the meter box and abuts an outer surface of the wall of the meter box or abuts a gasket sandwiched between the flange and the outer surface of the wall of the meter box. The cylindrical member, the flange, and the grommet all have aligned through-holes through which the power line passes as the power line enters the meter box.

A connector adapted to secure an electrical power line entering an electrical meter box, the connector comprising:
- a cylindrical member having a longitudinal through-hole, a first male threaded portion, and a second male threaded portion, the cylindrical member adapted to be at least partially inserted into the meter box through an access hole defined in a wall of the meter box;
- a flange affixed to or integral with a first end of the cylindrical member, the flange having a through-hole aligned with the through-hole of the cylindrical member, the flange adapted to remain outside of the meter box when the cylindrical member is at least partially inserted into the meter box, the flange adapted to abut an outer surface of the wall of the meter box or to abut a gasket sandwiched between the flange and the outer surface of the wall of the meter box;
- a connector nut that is left-handed threaded and threaded onto the first male threaded portion;
- a grommet nut having an inner surface that is female threaded and an inwardly protecting circumferential lip;
- a cupped washer, wherein the circumferential lip holds the cupped washer in place and the cupped washer in turn holds the grommet in place;
- and
- a cylindrical grommet having a longitudinal through-hole, the grommet selectively insertable at least partially into a second end of the cylindrical member and securable therein;
- wherein the flange through-hole, the cylindrical member through-hole, and the grommet through-hole are all adapted for the power line to pass as the power line enters the meter box.
A method of securing an electrical power line entering an electrical meter box, the method comprising:
- obtaining a connector comprising (a) a first cylindrical member having a longitudinal through-hole and a flange affixed to or integral with a first end of the first cylindrical member, the flange having a through-hole aligned with the through-hole of the first cylindrical member;
- (b) a second cylindrical member selectively attachable to a second end of the first cylindrical member and having a longitudinal through-hole aligned with the through-hole of the first cylindrical member and the through-hole of the flange;
- and (c) a cylindrical grommet having a longitudinal through-hole, the grommet selectively insertable at least partially into the second cylindrical member and securable therein;
- inserting the second end of the first cylindrical member through an access hole defined in a wall of the meter box until the flange or a gasket encircling the first cylindrical member adjacent the flange abuts the outer surface of the wall of the meter box, such that the flange remains outside the meter box;
- attaching the second cylindrical member to the first cylindrical member;
- inserting the grommet at least partially into the second cylindrical member;
- and
- inserting a power line into the meter box through the flange through-hole, through the first cylindrical member through-hole, through the second cylindrical member through-hole, and through the grommet through-hole.
