Used for splicing underground electric cables. Works well in principle, but does not work properly when using Romex underground cable. Romex has a flat and oval shape. The connector at each end of the plug is round. The zip tie that needs to be tightened to seal the cable hole will not work with Romex. However, I used it anyway and filled each end with silicone sealant. I wrapped the whole thing with several layers of insulating tape. Hope it works!
