B-Line Eaton series open racks, Aluminum, 43 mounting spaces, Telco gray powder coat, Includes #12-24 panel mounting holes, Self-supporting aluminum

43 mounting spaces means 43 rack units (43U) of usable panel height on an 84 inch tall frame. That is enough for, say, six 6U switch stacks plus patch panels, or a full run of patch panels and cable management in a telecom closet. Plan your U count before ordering, because the frame height is fixed at 84 inches.

Footprint is 20.31 inches wide by 15 inches deep, and it stands 84 inches tall. In a closet, allow working clearance front and rear on top of that 15 inch depth, since an open frame is cabled and serviced from both sides. Check your door opening and ceiling height before delivery.

The frame weighs 33 lb, built from aluminum and steel. That is light enough for a single tech to carry into a closet and stand up, which is the main reason people pick aluminum over a steel relay rack for upper-floor telecom rooms and retrofit work. The tradeoff is that equipment loading is what governs, not the frame weight.

An open frame like this 43 space aluminum rack gives you access from all four sides and free airflow, which suits patch panels, switches and cross-connect work in a locked telecom closet. Go to an enclosed cabinet instead when the equipment sits in an open or public area and needs to be locked, or when you need dust and airflow containment. Open racks give you no physical security of their own.

What ships is the relay rack frame itself, with the #12-24 tapped mounting holes. Vertical cable managers, shelves, power strips, grounding kits and mounting hardware for your gear are separate items, so add them to the order if the job needs them.

Finish is Telco gray powder coat, the standard gray used across telecom equipment rooms, so it lines up with typical existing relay racks and ladder rack in the same space. If your facility standard is black, this one will not match.
