Abstract: An improved liquid infiltration adapting structure for preventing liquid infiltration around a gate valve box. The structure has an annular tube structure that is tapered to more easily receive a mating pipe. The tube structure may also comprise at least one bead for further securing the mating pipe. The adapting structure is also improved by providing a stepped inner flange for ease of installing the structure around the gate valve box.

Abstract: An extension box for electrical condulets or junction boxes can be used by itself as a basic junction box in an electrical conduit system or as an auxiliary junction box coupled to a basic junction box to increase the interior volume of or extend a branch conduit system from the basic junction box. The body of the extension box has coupling hubs leading through the body walls to the body interior, for receiving ends of electrical conduits. Complementary male and female coupling formations are provided at the open front and back of the extension box body to permit two or more extension boxes to be coupled in stacked relation to a conventional junction box such as a condulet. Removable covers close the open back of the extension box.

Abstract: An adaptor for supporting a key box on an underground gate valve, the adaptor including a rectangular metal ring adapted to be seated on the gate valve bonnet flange, a number of radially extending arms positioned to engage the lower edge of the key box bonnet, and a resilient ring positioned between the adaptor ring and the key box flange.
