This Inlet Mounting Plate is designed for mounting their standard inlet in a 2 x 3 wall with drywall or plaster. This plate is not needed for the Hayden SuperValve since their unique mounting plate is packaged with the inlet.
Due to the limited space, a special Short 90° Spigot #765506W
is typically used directly behind the mounting plate. All other elbows, tees, etc. should be the sweep type so any object which is able to get through the short elbow should also pass through the others easily.
