Yes. The SB5561084TG is a 19 inch wide rack with 50 mounting spaces of usable rail height, so standard 19 inch EIA panels and chassis mount directly to the rails. It stands 84 inches tall.

The rails are punched with 12-24 panel mounting holes, so you need 12-24 rack screws and 12-24 cage-free hardware. Equipment supplied with 10-32 or M6 screws will not thread in, so order 12-24 screws and washers with the rack.

Yes, the SB5561084TG is built as a Seismic Zone 4 open duct unequal flange rack, which is why it is specified in central offices and data rooms in high seismic areas. It is also UL Listed. Floor anchorage and any overhead bracing still have to follow the structural engineer's detail for the room.

An unequal flange rack has one rail flange deeper than the other, which gives you a wider cable duct channel on one side of the upright for vertical cable runs and tie-off. On the SB5561084TG that is paired with a top angle style top for cable ladder or runway attachment. If you are cabling heavily from above, that is the version you want; an equal flange rack is the simpler choice where cable volume is light.

Open frame. The SB5561084TG is a two-post open rack, no side panels, no doors, no lockable enclosure. It gives full access to both sides of the equipment and free airflow, but nothing secures the gear physically, so in a shared or public space you want an enclosed cabinet instead.

Steel to ASTM A570 grade 33, finished in telco gray powder coat. That is the standard grey used through central office and MDF rooms, so it matches existing B-Line telco racks and ladder rack already in most of those spaces. Powder coat is not a corrosion finish for wet or outdoor locations, keep it to conditioned interior rooms.

No. What you get is the frame itself: uprights with 12-24 punched rails, top angle, 50 mounting spaces. Vertical cable managers, shelves, power strips, grounding kit and 12-24 hardware are all separate line items, so spec them alongside the rack if the job needs them.

The frame weighs 39 lb, so it is a one or two person carry even at 84 inches tall. Plan on a second set of hands to hold it plumb while you anchor the base, since an unloaded two-post rack is top-heavy the moment you start hanging equipment.

The footprint works off a 19 inch width, with a listed length/depth dimension of 84 inches and 84 inches of height. Add working clearance front and rear, since an open rack is serviced from both sides.
