COMMON TOOLS FOR INSTALLATION
The following tools are commonly used for installation of cable tray:
• Metal cutting saw
• Leveling device
• Touch-up material
• Tape measure
• Screwdriver
• Square
• Drill with bits
• C-clamp
• File
• Torque wrench
• Open end wrech
• Ratchet wrench
• Nylon cord or laser
• Offset Bolt cutters (Wire mesh)
• Sealant for cut edges (Fiberglass)
• Dust Mask (Fiberglass)
• Cutting Saw (Fiberglass) Carbide or Diamond Tipped
• Appropriate safety equipment
SUPPORT INSTALLATION
Caution! Do not cut or drill structural building members (e.g. I-beams) without approval by the general
contractor.
In order to install the cable tray supports, first find the required elevation from the floor to the bottom of
the cable tray and establish a level line with a laser or a nylon string. A string works well because it can
be used to align the threaded rods on one side of a trapeze and find the tops of the supports.
In order to speed the process of installing the trapeze hangers, some nuts may be pre-threaded onto the
threaded rod to the approximate location where the nut will be needed. One method for pre-threading the
nuts is to put the nuts onto the end of a piece of threaded rod, attach a drill to the threaded rod, and run
the nuts up the rod holding onto them with an open-end wrench.
NOTE—Nonmetallic supports and hardware may require special load bearing considerations due to material
composition and application temperature. Consult the cable tray manufacturer for recommended practices.
Cable Tray Supports
Caution! Supports for cable trays should provide strength and working load capabilities sufficient to meet
the load requirement of the cable tray wiring system. Consideration should be given to the loads
associated with future cable additions or any other additional loads applied to the cable
tray system or the cable trays support system.
NOTE—Nonmetallic supports and hardware may require special load bearing considerations due to material
composition and application temperature.
NOTE—Special consideration may be required for center-supported systems considering eccentric loading.
