B-Line Eaton series open racks, Double sided, Steel, Flat black powder coat, 12-24 panel mounting holes, 39 mounting spaces, Top channel style, Seiem

The rails come with 12-24 panel mounting holes, so equipment is fastened with 12-24 rack screws. You do not need cage nuts, and you will want to order 12-24 screws separately since equipment rarely ships with the right thread.

It is built as a seismic zone 4 network bay open duct rack, which is why the frame is 11 gauge steel to ASTM A1011SS. Anchoring to the slab per the local structural detail is still required for the seismic application.

The top channel gives you a structural cross member at the head of the rack to land overhead cable runway and to tie adjacent bays together, which matters when you are ganging several bays into a network row rather than setting a single standalone rack.

Double sided refers to the duct configuration on the network bay rack, with vertical cable duct on both sides of the 19 inch mounting space. It keeps patch cord bundles off the equipment faces on each side instead of running everything up one channel.

Yes, the SB5571084FB carries a UL Listing, which is what most institutional and government specs call for on telecom bay hardware.

An open duct rack like the SB5571084FB is the right call in a secured telecom or MDF room where you want maximum access to both sides of the equipment and free convection airflow. Choose an enclosed cabinet instead when the space is shared or public and you need lockable doors and side panels, or when you need to control airflow and dust around the gear.

Empty weight is 91 lb. That is a two-person lift and stand, and it is worth noting on the freight paperwork since it ships as a rigid 84 inch steel frame rather than flat packed hardware.

Flat black powder coat over steel, the standard finish on B-Line network bays, so it lines up visually with other flat black open frame racks and ladder rack in the same room.
