RackSolutions engineering team has custom designed a 2 post rack that can easily be converted into a 4 post rack. Our rack is constructed from 13 gauge steel, NOT aluminum, and features square mounting holes on the frame. Equipped with tool less button-mounting holes along the sides, vertical PDUs and cable managers can be easily installed. The TechEdge 2 Post Rack was designed with the capability of easily converting into a 4 post rack with the addition of our conversion kit available for the 25U and 45U. Our universal design is compatible with most rack equipment and stands out from the rest with the option to add on our caster kit for easy transportation in your server room, office, or studio. It's easy to reposition or relocate the rack in order to connect your rack-mounted equipment to other devices throughout your work space. If you're looking for a more permanent solution, the rack comes with a floor anchor kit to secure your rack to a certain area.
