The DataFrame family of welded 19" vertical rack cabinets offers Compaq compatibility. The units’ mounting rails are made of much heavier 12-gauge steel, allowing most chassis to be shipped installed in the cabinet. Equipment mounting rails have both 1-cm2 mounting holes and traditional 0.281" round holes. Rails can be reversed to accommodate users’ chassis and are adjustable front-to-back to ease installations. The cabinet door exceeds the Compaq cooling specification, and the angled door design allows flush side-by-side cabinet mounting with proper clearance using a simple bolt-together kit. Flush cabinets can still have locking front and rear doors. All DataFrame cabinets come assembled and fit through a standard 7' office door. Cabinets are available in 36U and 40U configurations with cabinet depths of 31" and 36". Applications are rack-mount servers and networking equipment, for example.
