B-LINE SB212718AYZ – Frequently Asked Questions
1) What does the B-Line SB212718AYZ runway center support hanger kit do in a cable runway installation?
It's a center support hanger kit for cable runway, used to hang a run of runway from above between end supports so long spans don't sag under cable load. The kit is B-Line Eaton part SB212718AYZ, made from ASTM A36 steel with a yellow zinc finish, and it is UL Listed.
2) Is a yellow zinc runway hanger OK for an outdoor or damp telecom space?
Yellow zinc plating over ASTM A36 carbon steel is an indoor finish. It suits conditioned equipment rooms, data centers and telecom closets. For exterior, wet or corrosive locations, specify a hot dip galvanized or stainless runway support instead of the yellow zinc SB212718AYZ.
3) How much weight do I have to allow for when anchoring this B-Line runway hanger to the structure above?
The kit itself weighs 4.9 lb, so the dead load your threaded rod and overhead anchor carry is that plus the runway section and cable bundle it supports. Size the rod and anchors for the cable fill, not for the hardware.
4) Is the B-Line SB212718AYZ hanger kit UL Listed for electrical work?
Yes, the SB212718AYZ runway center support hanger kit is UL Listed, which is typically what an institutional or government spec asks for on cable support hardware.
5) Do I need one of these per runway run, or several?
Center supports are intermediate hangers, so quantity depends on span. You order end or wall supports for the terminations and then place center support kits like the SB212718AYZ at intervals along the run to keep the runway from deflecting. On a short run between two supported ends you may need none; on a long overhead run you will need several.
6) Does the B-Line runway center support hanger kit come with threaded rod and anchors?
What ships is the hanger kit, ASTM A36 steel with yellow zinc finish. Overhead threaded rod, and the concrete or steel anchor to attach it to the deck, are sized to your structure and ordered separately.
7) Is there more than one version of this B-Line hanger kit to choose from?
It is a single configuration: model SB212718AYZ, yellow zinc ASTM A36 steel. There are no finish or size options to specify, so the only decisions left are quantity and the rod and anchor hardware above it.
