Metallics TRS9/3 – Frequently Asked Questions
1) Will the 1/2-13 threaded rod work with 1/2 inch beam clamps and strut hanger hardware?
Yes. Hanger hardware sized 1/2 inch (beam clamps, strut nuts, rod couplings, split ring and clevis hangers) is threaded 1/2-13, which matches the TRS9/3 rod exactly. Nothing is supplied with the rod itself, so order the nuts, washers, and clamps separately.
2) How many pieces of threaded rod come with the Metallics TRS9/3?
One piece. The TRS9/3 is sold by the piece, not bundled or by the box, so a run of ten drops means ten pieces.
3) Is zinc plated threaded rod suitable for outdoor or wet locations?
Zinc plated steel is a mild corrosion coating meant for dry interior use, which covers most conduit, cable tray, and strut hanging. For exterior, wash-down, coastal, or corrosive environments, step up to hot dip galvanized or stainless rod in the same 1/2-13 thread instead.
4) I need longer than 3 feet for a high ceiling. Can I join two pieces of this rod?
Yes. Two TRS9/3 pieces joined with a 1/2-13 coupling nut or rod coupler give you a continuous drop longer than 3 feet. Thread each rod in to roughly half the coupler length so the joint carries properly, and brace long drops laterally as the job requires.
5) Can I cut the 3 foot threaded rod down to shorter drop lengths?
Yes, 1/2-13 zinc plated rod cuts cleanly with a bandsaw, chop saw with an abrasive wheel, or a rod cutter. Run a nut off the cut end to clean up the thread, and touch up bare steel at the cut if the location is at all damp.
6) What is the Metallics part number for a 1/2 inch by 3 foot threaded rod?
TRS9/3 is the Metallics part number for the 1/2-13 by 3 foot zinc plated steel threaded rod.
