B-Line Eaton series open racks, Aluminum, 45, Mounting spaces: 43, Aluminum - brushed, Two-post equipment rack

Frame dimensions are 20.31 inches wide by 15 inches deep, so it takes a narrow floor footprint and suits a closet or small IDF room. Because it is a two-post open rack with no base cabinet, deep or heavy gear needs to be supported at both ends or bolted to the floor and braced overhead.

A two-post rack like this aluminum B-Line unit carries equipment at the front rails only, which works for patch panels, switches, and shallow rack-mount gear. Deep chassis, UPS units, and servers want a four-post rack or an enclosure with rear rails, since a two-post frame supports only one end of the load. At 33 pounds for the whole frame, this one is aluminum and steel construction built for light density installs, not heavy server stacking.

Order by manufacturer part number SB558084XUAL, the Eaton B-Line series open frame two-post rack, 84 inches tall, 43 mounting spaces, brushed aluminum. That is the single configuration under this number.

What you get is the two-post frame itself. Vertical cable managers, horizontal wire management panels, shelves, power strips, and floor anchor hardware are separate line items on an open rack build, so budget those alongside the frame. The 15 inch frame depth leaves you working in open air on both sides, which is why side-mounted vertical managers are the usual companion.

Finish on this one is brushed aluminum, an unpainted mill look. If your existing racks are black powder coat, this will not match visually, though the 43U EIA hole spacing means your panels and equipment mount the same way either way. For visible lobby or classroom installs where appearance matters, standardize the finish across the room.

The frame weighs 33 pounds, so a single installer can handle and stand it, which is one of the reasons for aluminum over an all-steel frame. It still needs floor anchoring once positioned, and the loaded weight of your gear is what governs the anchor hardware.
