B-Line Eaton series double sided 30 inch shelf width distribution , 138" height, 43.62" length, 30" width, 5 vertical with 16 shelves, ASTM A36 struct

This Eaton B-Line frame is built to support terminal blocks for central cross connects, the main cross-connect field in a telecom room where incoming cable terminates and jumpers run out to the building. Double sided means blocks mount on both faces of the 30 inch wide shelf, roughly doubling termination capacity in the same floor footprint. Choose it when the frame stands free in the middle of a room and can be worked from both sides. If the frame has to go against a wall, a single sided frame is the right call since one face would be unreachable.

Five verticals with 16 shelves total. That gives you 16 horizontal mounting levels across a 43.62 inch length for terminal block fields, with the 5 verticals carrying the load and providing the vertical cable paths between levels. Plan your block layout and jumper routing around those five uprights.

What you are ordering is the frame itself, model SB60413805TG: the steel structure with 5 verticals and 16 shelves finished in Telco gray. The terminal blocks, protector modules, jumper wire, cable management, and floor and ceiling anchoring hardware are specified and ordered separately to suit the cross-connect design in your room.

ASTM A36 structural steel with a Telco gray powder coat. A36 is the standard mild structural steel grade, so this is a welded/bolted structural frame rather than light formed sheet, and Telco gray is the conventional finish for central office and telecom room equipment, so it will match existing frames and racks in a standard MDF room.

No certification applies to this frame. It is a structural steel support frame for terminal blocks, not an electrical device, so it is not a listed product. The steel itself is specified to ASTM A36, which is the material standard behind it.
