B-Line Eaton series double sided 18 inch shelf width distribution , 120" height, 31.62" length, 18" width, 8 vertical with 13 shelves, ASTM A36 struct

609 lb for the frame itself, before any terminal blocks, cross connect wire or shelf contents. That is a two-person-plus-equipment unload, and on a raised access floor you will want the load spread or the frame set on stringers over pedestals. Slab-mounted installs are the straightforward case.

It supports terminal blocks for central cross connects, the mass termination point where riser and horizontal copper meet in a telecom or MDF room. Double sided means blocks mount on both faces of the frame, so you get twice the termination capacity in the same floor footprint, but you must leave working access on both sides rather than pushing it against a wall.

The configuration is 8 vertical with 13 shelves, so you have eight vertical uprights carrying thirteen shelf levels of block mounting space, available on both faces. If your block count is lower, a smaller vertical or shelf count in the same B-Line series is the cheaper buy; this is the high-density end of the range.

18 inch shelf width, which matches the 18 inch overall frame width. Check the footprint of the connecting blocks you are standardizing on before ordering, since block rows sized for a wider shelf will overhang.
