To secure computer and network systems without completely encasing them in steel, a good alternative would be Steel Relay Racks from Vericom Cabling and Communication Solutions. Constructed out of corrosion resistant, powder-coated steel, this structure can support several shelves with its multiple channels. There are RMU markings along the Vericom relay racks to speed up mounting of components.
Adjustable feet allow for stability on uneven floors and adaptability to individual environments. There is space at the bottom of the two post relay rack for placement of large devices better suited on the floor. There is no restriction of air flow, so ventilation is readily available, keeping devices from overheating and losing operative performance. Expansion packs are also available to turn these Two Post Steel Relay Racks into Four post racks.
