B-Line Eaton series double sided 30 inch shelf width distribution , 138" height, 43.62" length, 30" width, 8 vertical with 16 shelves, ASTM A36 struct

It is the steel skeleton that supports terminal blocks for central cross connects, typically in a telco or main distribution room. Double sided means blocks mount on both faces of the frame, so you get twice the termination field on the same floor footprint and technicians work from front and back. The SB60413808TG is configured with 8 verticals carrying 16 shelves.

Sixteen shelves across 8 verticals, with a 30 inch shelf width. That is two shelves per vertical, and the 30 inch width matches the overall frame width, so your block mounting field is 30 inches across per bay.

Order Eaton B-Line part number SB60413808TG. That number covers the double sided 138 inch high frame, 43.62 inch depth, 30 inch width, with 8 verticals and 16 shelves.

Because it is double sided, technicians work both faces, so you need clear aisle on the front and back rather than wall mounting it. The frame is 43.62 inches deep and 30 inches wide, so lay out your room for that footprint plus working aisles on two sides, and account for the 138 inch height when routing overhead cable runway above it.

ASTM A36 structural steel with a Telco gray powder coat. A36 is the common hot-rolled structural grade, which is why the frame carries heavy block loading at this height, and the powder coat is the standard telco equipment room color if you are matching existing frames and racks.
