Vertical Stack Fittings for Hub and Spigot Systems

This no-hub inlet stack fitting is recommended for use with a floor mounted back outlet water closet. It features a 4" Spigot Connection With 2" Vent Hub. Selecting the proper vertical stack fitting is of prime importance since that fitting with side inlets is the start of the horizontal battery of fittings and supports. To determine left or right hand fitting, face the stack from the fixture side of the wall. If the inlet is to the left of the stack, it is a left hand fitting. If the inlet is on the right of the stack, it is a right hand fitting. The vent is always located on the same side as the inlet on a single inlet stack fitting.
