B-LINE SB117AYZ – Frequently Asked Questions
1) What does a runway retaining post like the B-Line SB117AYZ actually do on a cable runway?
The SB117AYZ is a vertical post that mounts to cable runway (ladder rack) stringers to raise the effective sidewall height, so you can stack cable higher without it spilling over the side. Eaton B-Line lists its application as increasing the cable capacity fill of the runway. It is a retaining post only, not a support or a bend radius device.
2) How much extra cable height do I get with the B-Line SB117AYZ retaining post?
The post stands 8.5 inches tall, so it extends the usable stacking height of the runway sidewall by roughly that much above the mounting point. Footprint is small: 1.5 inches deep by 1.3125 inches wide, so it does not eat into the tray width where your cable actually runs.
3) Is the yellow zinc finish on this B-Line post okay for a data center or telecom room?
Yellow zinc plated A513 steel is a general indoor finish, which is what the SB117AYZ is built from. It suits conditioned spaces like MDF/IDF rooms, telecom closets and data halls. For damp, washdown, or exterior runs, specify a hot dip galvanized or stainless retaining post instead, because zinc plating is a light corrosion coating only.
4) Is the B-Line SB117AYZ retaining post UL Listed?
Yes, the SB117AYZ carries a UL Listing. That matters on jobs where the inspector or the spec calls for listed components throughout the cable pathway rather than just on the runway sections themselves.
5) Will this post work on someone else's ladder rack, not Eaton B-Line runway?
The SB117AYZ is an Eaton B-Line series accessory sized for B-Line runway stringers. Fit on another manufacturer's ladder rack depends on that stringer's profile and hole pattern, which is not something to assume. If you are running non B-Line rack, match the retaining post to the rack brand you already have up.
6) Does the B-Line SB117AYZ replace a cable runway sidewall or add to it?
It adds to it. The post is a bolt-on accessory that raises retention height on existing runway, not a structural component. The runway stringers still carry the cable load; the post just keeps the upper layers of cable from rolling off the side.
