44U to 48U Server Rack Cabinets

48U is a common rack height sold for data centers. 48U = 48 Rack Units on your Mounting Rails = 84" of rack mount space available. Please note that actual internal and external height vary depending on the server cabinet manufacturer. Depending on your application, requirements, and space limitations; a smaller, more specialized cabinet may be best for your needs. Though it may be intuitive to think that a smaller rack would be less expensive because of less steel being used, server cabinets in the 48U height range are mass produced and therefore usually have far less production cost.

Which is the best 44U - 48U Rack for me?
Comparing racks can be a daunting task. Even comparing racks with similar dimensions can be like comparing apples to oranges. In addition to your dimension requirements, please also take into consideration the rack's cooling capabilities and cooling options, compatibility, load capacity, cable management options, rack accessories, rail mounting, and overall rack expandability. For additional help, please contact our expert sales engineers at 1-866-722-5776 or join us on Live Chat.

Being within a few rack units, you may also want to consider 42U Server Racks.
