Abstract
A watertight enclosure for use in an outdoor junction box for use in housing electrical connections such as solar panel installations includes a mating base and cover. The base is bounded by an upstanding peripheral wall having a channel profiled in the top. The mating cover has an outwardly facing channel formed by upper and lower peripheral parallel flanges. The lower flange on the cover fits into the channel in the box member and the upper flange overlaps the outer wall leaving a slight gap providing the only opening to the otherwise enclosed duct about the periphery of the assembly. Wires passing through bores in the upstanding wall are sealed by compressing elastomeric spheres which bore into conformity with the wires passing therethrough.
