B-Line Eaton series double sided 18 inch shelf width distribution , 108" height, 31.62" length, 18" width, 3 vertical with 12 shelves, ASTM A36 struct

Three verticals with 12 shelves, in the 18 inch shelf width configuration. That gives you four shelf positions per vertical bay across the double sided assembly for mounting terminal blocks. If your cross connect count needs more or fewer positions, B-Line builds this same series in other vertical and shelf counts, so order by the configuration that matches your block schedule.

No. The SB60210803TG ships as the frame itself, three verticals with 12 shelves in steel, and it is built to support terminal blocks for central cross connects. The blocks, block mounting hardware, cable management, grounding kit, and floor anchors are separate line items you add to the order.

Frame is ASTM A36 structural steel with a Telco gray powder coat, the standard finish for central office and building distribution frames so it matches existing ironwork in a telco room. A36 is a mild structural steel, so the powder coat is what protects it. Keep it to dry indoor spaces, mechanical rooms, riser closets, and equipment rooms, not damp or exterior locations.

Go double sided, like the SB60210803TG, when the frame sits out in the floor and techs work both faces, which doubles termination capacity per square foot of room. Choose a single sided frame when it must go flat against a wall, because the back face becomes unreachable and you lose half the shelves you paid for. The deciding factor is whether you can leave working clearance on both sides of a 31.62 inch deep unit.

Eaton does not attribute a certification to this frame, so treat it on a submittal as ASTM A36 structural steel construction with a Telco gray powder coat finish, ordered by manufacturer part number SB60210803TG. Spec it on its configuration and materials rather than on a listing mark.
