B-Line Eaton series open racks, Aluminum, Rack width 23, Mounting spaces: 49, Aluminum - brushed, Self-supporting aluminum relay rack

No. The SB558096AL is a 23 inch rack, so it takes 23 inch wide panels and equipment, which is the telecom standard rather than the 19 inch EIA width used by most IT gear. If your hardware is 19 inch, you either need a 19 inch rack or 19-to-23 inch adapter brackets.

It is a self-supporting aluminum relay rack, so the frame stands on its own base once anchored to the floor rather than relying on wall or overhead ladder rack support. At 96 inches tall with a 15 inch footprint depth, floor anchoring is still how you keep it stable under loaded equipment.

49 mounting spaces across the full 96 inch height. That is the count to work from when you lay out patch panels, splice trays and active gear, since an open relay rack gives you the whole face without doors or side panels eating into the usable area.

An open frame like this 23 inch aluminum relay rack is what you use in a secured, climate-controlled telecom or MDF room where you want unrestricted access to both sides for cross-connects and cable dressing. An enclosed cabinet is the better call when you need physical security, dust control, or airflow management in a shared or public space. Open frames also keep the weight down: this one is 36 lb.

The SB558096AL is built from aluminum and steel and weighs 36 lb, which is a big difference when a two-man crew has to carry a 96 inch frame up a stairwell or into a crowded closet. Aluminum also doesn't rust, which matters in damp basements and unconditioned spaces. Steel racks carry more weight, so for heavy battery strings or dense server loads spec steel instead.

Footprint works out to 23 inches wide by 15 inches deep. Add your own aisle clearance front and back, since an open relay rack is worked from both sides and equipment plus cable management will overhang the 15 inch frame depth.

The finish is brushed aluminum, the natural mill look rather than a painted black or grey. If your existing lineup is black powder-coated steel, this frame will not visually match it, so on a row expansion in a visible space that is worth checking before you order.
