Abstract
Abstract An improved electrical junction box particularly suitable for outdoor use is provided. The junction box contains a plurality of mounting holes each of which is closed by a grommet. The mounting holes are defined within lugs having raised and depending portions with a flange extending therebetween. The grommet is provided with a circumferentially extending groove into which the lug flange seats. Counterbores extend from the top and bottom end of the grommet terminating short of each other whereby to define a web section. The grommet groove extends about the web.
