B-Line Eaton series runway retaining post, Used to increase cable capacity fill of mounts, Mounting brackets, Cable retaining post, Telco gray powder

The SB12608EW retaining post bolts onto cable runway mounting brackets to raise the side wall, so you can stack more cable on the same mount without it spilling over the edge. Eaton lists its purpose as increasing the cable capacity fill of mounts. It is a post only, not a bracket or a runway section, so it goes on hardware you already have in place.

It measures 8 in high, 1.5 in wide and .375 in deep, so it adds 8 inches of vertical retaining height above the mount it attaches to. That is the number to work from when you are sizing how deep a cable bundle the runway will hold.

Yes, the post is UL Listed. That matters on jobs where every piece of the cable support pathway has to be listed hardware, which is common in carrier spaces and institutional data rooms.

The SB12608EW is the retaining post itself. It is meant to be added to runway mounting brackets, so you need the brackets and runway already mounted, plus the appropriate hardware to fasten the post to them. Order posts per mount location, not per runway run.

Telco gray powder coat, which is the standard B-Line runway color used across their cable tray and ladder rack line. If your existing runway and mounting brackets are the gray telco finish, this post blends in; if you are running black or zinc pathway, it will not match visually.

Each post weighs .78 lb. Negligible against the cable load itself, but worth counting when you are adding posts at every mount across a long runway and totaling the load on the threaded rod or wall supports.
