B-Line Eaton series double sided 18 inch shelf width distribution , 108" height, 31.62" length, 18" width, 4 vertical with 12 shelves, ASTM A36 struct

283 pounds bare, before any terminal blocks, cable, or cross connect wire goes on it. That is a two-person minimum lift, and it is heavy enough that it should be floor anchored and, in most telecom rooms, braced overhead or to an auxiliary framing channel. Check the floor loading in your room before you set a row of them.

It is the steel skeleton that supports terminal blocks for central cross connects, the point where incoming cable is terminated and jumpered to house wiring. Double sided means shelves face both directions off the same uprights, so you can terminate incoming on one side and distribution on the other and cross connect between them. The SB60210804TG carries 4 verticals with 12 shelves.

Pick the double sided frame when you are doing central office style cross connect work and need terminating space on both faces off one footprint, as with this 4 vertical, 12 shelf unit. A single sided rack or wall mount frame is the better call for a small cross connect field, a closet where you cannot get behind the frame, or where you are mounting rack-unit equipment rather than terminal blocks. The 31.62 inch depth here assumes you can work both sides, so it wants aisle space front and back.

Steel construction, described as ASTM A36 structural steel in Telco gray. That is the standard structural mild steel used for loaded distribution ironwork, and the Telco gray finish is the conventional colour for central office and equipment room frames, so it will match existing ironwork in most telecom spaces. It is an indoor, dry-location frame.

Shelves are 18 inches wide, matching the frame's 18 inch width, and there are 12 of them spread across the 4 verticals over the 108 inch height. Size your terminal block field against that 18 inch usable shelf depth per side before you lay out the cross connect.

One configuration, ordered as model SB60210804TG. The double sided arrangement, 18 inch shelf width, 108 inch height, 4 verticals and 12 shelves are all fixed in that part number, so there is no shelf count or height option to specify. Terminal blocks, cable rack, and anchoring hardware are separate items.
