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 cable-gland system provides a sealing function to openings in an electronic chassis that receive cables. The cable-gland system comprises a plurality of individual cable glands. Each of the plurality of individual cable glands includes an exterior end to be positioned adjacent an exterior of the chassis, and an interior end for positioning within the chassis.
