276-Series PVC Slab Penetration
The HOBBS 276-Series Stainless Steel Slab Penetration provides a female threaded, noncorrosive penetration through the pool floor or wall, terminating flush with the water-side surface. The threaded ends of the fitting allow for a wide range of piping materials to be used at the pipe connection end, and a wide range of functions at the pool end, including use as a suction or ballast point (in conjunction with various 230- Series Plates), and to install various spray effects.

Hobbs 275 Series Slab Penetrations are used for 3" and 4" pipe connections.
