B-Line Eaton series open racks, Aluminum, Mounting spaces: 43, Telco gray powder coat, Self-supporting aluminum relay rack

The SB558084AL aluminum relay rack gives 43 mounting spaces over an 84 inch overall height. That is enough for a full run of patch panels, switches and rack-mount UPS gear in a telecom or IDF room without stacking a second frame.

It is a self-supporting design, so it stands on its own base rather than depending on a wall or overhead ladder rack for stability. Standard practice is still to lag the base to the floor, and the 15 inch base depth gives you the footprint to do it.

Footprint is 20.31 inches wide by 15 inches deep, standing 84 inches tall. Lay that out with clearance front and rear before you commit, since an open frame is worked from both sides.

The SB558084AL is built from aluminum and steel and weighs 33 pounds, which is a fraction of an all steel frame of the same height. That matters when you are carrying a rack up stairs or into a finished closet, or where floor loading is a concern. For very heavy loads such as multiple full-depth servers or large battery strings, a steel frame or a four-post enclosure is the better call; an aluminum two-post relay rack is aimed at patch panels, switches and lighter telecom gear.

Order it as B-Line SB558084AL. That is the 84 inch tall self-supporting aluminum relay rack in telco gray, 43 spaces.

Telco gray powder coat, the standard light gray used across telecom and data closets, applied as a powder coat rather than a wet paint. It matches the finish on typical ladder rack, cable runway and adjacent B-Line frames, so a rack added to an existing room will not stand out.
