Sigma Engineered Solutions Metal Weatherproof New work Box extender Electrical Box
Does this extender have a threaded hole appropriate for a grounding screw?
1
The square tab near the top right of this 1-Gang Metal Box Extender (Item #69765 Model #14233) is appropriate for a grounding screw, which is not included. The ground screw hole in this extender would pair nicely with 1-gang metal boxes similar to (Item #72238 Model #14251) where the ground screw holes would align. The box's pre-installed grounding screw can be removed and reinstalled through both aligned ground screw holes once the extender is attached.
