B-Line Eaton series open racks, 3" height, 3.5" length, 19" width, A569 steel, Rack mounted horizontal cable management panels, Flat black powder coa

Yes. The SB719192XLFB horizontal cable management panel is built to a 19 inch width, which is the standard EIA rack and open frame rack mounting width, and it ships with 12-24 mounting hardware so you can bolt it straight to tapped rack rails.

It stands 3 inches tall, so budget roughly 2U of vertical rack space (a rack unit is 1.75 inches). Depth off the rail face is 3.5 inches, which matters if you have a shallow wall-mount frame or a door in front.

No. The SB719192XLFB includes 12-24 mounting hardware in the box. If your rack rails are tapped 10-32 or use cage nuts instead, that included hardware won't thread and you'll need to source the matching size.

This Eaton B-Line panel mounts horizontally across the rack and is positioned to route and hold wire bundles, keeping patch cords off the equipment faces and out of the airflow. Common practice is one between each patch panel and its switch so jumpers have somewhere to break out; on a dense two-post run you'll want several stacked down the rack rather than one at the top.

It is part of the Eaton B-Line open frame rack line and mounts to the 19 inch rail face, so a two-post open frame rack is exactly what it's intended for. It will also mount in a cabinet as long as you have 3.5 inches of clear depth behind the rail for the panel body.

The panel is A569 steel with a flat black powder coat finish, black throughout. Powder coated steel is the standard build for indoor rack hardware and matches the typical black open frame rack, so it blends in on a run of mixed equipment.

At 1 lb it's a one-person install. Hold it to the rails, start the included 12-24 screws, and torque down; no support bracket or second set of hands needed.
