B-Line SB5779096YZ Eaton series open frame racks, Steel, Yellow zinc, 12-24 panel mounting holes, 75 mounting spaces, Top channel style, Seismic Zone 4, network bay closed duct rack, 11 gauge steel, ASTM A1011SS

75 mounting spaces on a 96 inch tall frame. That is a full-height network bay, so plan your ceiling clearance and any overhead cable runway before you set it. Panel mounting holes are 12-24 tapped, so your gear screws in directly without cage nuts.

Yes. The SB5779096YZ is built as a Seismic Zone 4 network bay closed duct rack, and it is UL Listed. It is also 11 gauge steel to ASTM A1011SS, which is the structural grade sheet that gives the frame its stiffness under lateral load.

Width is 23 inches and the length/depth figure is 96 inches, with an overall height of 96 inches. Lay it out with front and rear service access, since an open frame rack is worked from both sides.

They will. The rails carry 12-24 panel mounting holes, the standard tapped thread for telecom panels and rack-mount network gear, so screws go straight into the rail. You supply the 12-24 rack screws to match your equipment.

124 pounds shipping in as a frame. Treat it as a two-person set for a 96 inch tall assembly, both for the weight and for keeping it plumb while you anchor the base. In a Seismic Zone 4 job it has to be floor anchored per your structural detail before any gear loads go on it.

Top channel means the frame is tied together by a channel across the top rather than a solid cap, which gives you a structural member to bolt overhead cable runway or ladder rack to and leaves the top open for cable entry. On the SB5779096YZ that channel is part of the Seismic Zone 4 frame, so use it as intended rather than cutting it.

An open frame bay like the SB5779096YZ is the choice for a secured telecom room where you want full access to both sides of every panel and free air movement, and where the closed duct verticals handle cable management. Go to an enclosed cabinet instead when you need lockable physical security, dust control, or a shared space where people other than your techs can reach the gear.

Yellow zinc over steel is a plated finish, intended for dry indoor use like an MDF, IDF, or telecom room. It is not a coating for outdoor or washdown environments. If your room is conditioned, it is the right finish and it bonds well for grounding continuity.

Order it as B-Line SB5779096YZ, the Eaton B-Line series open frame rack in yellow zinc. The YZ suffix is the yellow zinc finish, so do not substitute a black or plain variant if the spec calls for zinc plating.
