TRAFFIC
FUNCTION
The top specified must be strong enough to safely
carry the loads of anticipated traffic. The
regular Frank Pattern nickel bronze top is a
heavy duty design and can be used for all finished
floor areas subject to foot and light vehicular
traffic . For unfinished floors, subject to
heavy vehicular traffic, round, heavy duty cast
iron tops should be specified. Frank Pattern
has available cast iron tops in heavy duty design
and non-tilt tractor type covers.
MATERIAL
For most finished floors, the Frank Pattern
scoriated non-skid nickel bronze tops are recommended.
Nickel bronze has excellent corrosion resistant
qualities, is extremely serviceable, will not
discolor and has an attractive surface. Nickel
bronze tops will not rust stain the surrounding
finished floor area as cast iron tops sometimes
do. The "scuff-buff" action of foot traffic
passing over a nickel bronze top will actually
add to its appearance, giving it a soft patina.
Tops are available in special polished cast
bronze, for use where tops must blend with other
architectural trim.
SELECTION
OF BODY
Outlet Type - Bodies which are used with adjustable
floor level cleanout assemblies are available
with two types of outlet connections. No-Hub
and Instant-Set which can be effectively used,
depending on the type of piping used in the
system and compliance with plumbing code stipulations.
