Trays can be installed parallel to and against a wall or can be suspended from the building
structure using ATR. They can also be supported using channel stock or manufacturer specific
supports.
10) Install conduits.
See subclause 2.2.4.2, subclause 2.2.4.3 and TIA 569-B for maximum length of conduit and
bends between pull points and pull box sizing.
All metal conduits installed for the placement of telecommunications cable will be bonded to
the equipment grounding system.
All conduits shall have a pull string installed.
11) Conduit hangers.
Conduits are suspended from the building structure using a variety of hangers. These hangers
are available in many sizes and types depending on the type of conduit and method used to
install the hangers. Refer to the manufacturer’s specifications for use of the type and size for
the conduit hanger to be installed.
12) Installing wireway.
Wireways are different from cable trays in that they are completely enclosed pathways. They
usually feature a hinged cover or one which snaps in place. They are available in a number of
sizes and shapes, depending on the manufacturer. As with cable trays, the installation
methodology is directly related to the manufacturer’s guidelines. All metallic wireways
installed for the placement of telecommunications cable shall be bonded to the equipment
grounding system.
13) Pathway documentation.
The pathway shall be identified on the construction drawings and physically marked with a
label that identifies it and states its origin and terminus. (See ANSI/TIA 606-A.)
14) General housekeeping.
It is important to clean up after a work operation when installing pathways. In general,
equipment of sufficient size is required to install pathways and the materials are bulkier –
thereby taking up space in the hallways and passageways of the building. This causes
congestion and, if left in place, can impact the work efforts of others.
Hangers, their associated hardware, anchors, screws, and other materials can present a safety
hazard to workers and should be stored during work operations and upon completion of the
day’s activities. If a work area cannot be cleaned, safety cones and barricades should be placed
to prevent accidental intrusion into the work area by others until the work is complete and the
area is cleaned.
