B-Line Eaton series single sided distribution , 120" height, 100" length, 9.25" width, 8 vertical with 13 shelves, ASTM A36 structural steel, Telco gr

This is a universal distribution frame, single sided, built to support terminal blocks for central cross connects, the classic MDF/IDF arrangement where 66 or 110 blocks mount on the shelves and jumper wire runs between them. Single sided means blocks mount on one face only, so it can sit against a wall and you work it from the front. A double sided frame carries blocks on both faces for roughly twice the termination count in the same floor length, but it has to stand free in the room with working clearance on both sides. If you are lining a wall in a telecom closet, single sided is the right configuration.

It is configured with 8 verticals and 13 shelves. That shelf count is what sets your termination capacity, since the terminal blocks mount to the shelves, and the 8 verticals are what break up the 100 inch length into bays for cable management and jumper routing. If your block layout calls for a different shelf density, that is a different frame part number, not a field change.

What you are buying is the frame itself: the steel verticals, the 13 shelves and the structural members in Telco gray. The 66 or 110 blocks, block mounting brackets, jumper troughs, ground bar and floor anchors are specified and ordered separately based on your termination plan. Work out block type and count first, because that drives whether 13 shelves across 100 inches gives you the capacity you need.

Order it as B-Line SB60912008TG. That single part number covers the whole configuration: 120 inch height, 100 inch length, 9.25 inch width, 8 verticals, 13 shelves, single sided. There are no options to select on top of it, so if any of those dimensions do not match your drawing you need a different frame number rather than a variant of this one.

The frame is ASTM A36 structural steel with a Telco gray powder coat. A36 is the standard hot-rolled structural grade, so the channel and angle stock is drilled and bolted rather than formed sheet, and the gray powder coat is the usual finish match for central office and telecom room equipment. It is an indoor, dry-location finish, not a coating meant for exterior or corrosive environments.
