LB fittings
Right angle connectors which are used in conjunction with conduit so that you can bring cable through the wall of a house. These special connectors have thick gaskets and metal cover plates or are made of PVC so that they are moisture proof.  Typically, the fitting routes cable in the direction of a trench that has been dug from the house to the area where the electricity is needed. These fittings are threaded on both ends. Conduit which passes through the house wall to the exterior is screwed to one end and the conduit leading down the side of the house to the trench is screwed to the other end. This provides an enclosed environment from house to ground.
