Fixtures which are wall mounted and have no external contact with the finished floor are classified as “off the floor plumbing fixtures.” Fixtures so mounted are supported on concealed cast iron or steel supports (carriers). These supports are completely concealed in the wall, and support the load of the fixture by means of a suitable face plate and base support which is firmly anchored to the floor. Thus the load of the fixture is effectively taken off the wall and transmitted to the floor.

By incorporating a waste fitting which functions in conjunction with the support section, an entire system of “Combined Fixture Supports and Waste Fittings” has been developed. Thus, when mounting “off the floor” water closets, a complete unit is available which supports the fixture and includes a fitting which will tie into the drainage piping system. Fittings are available in vertical and horizontal patterns. Used in combinations, these fittings can satisfy waste and vent requirements of most systems. Smith engineers have worked closely with plumbing designers, contractors and code officials to develop a system which meets their rigid demands and requirements. Particular attention was given in design so that:

• the engineer can select supports with fittings to meet all problems created by architectural, structural, code or esthetic requirements.
• the plumbing contractor can easily and economically install a rigid and code approved support with fitting, which will function for the lifetime of the building.
• the code official is assured that fittings used with supports are designed to meet code requirements relative to the proper sizing for drainage piping and venting.
