Overall Height of Subracks / Card Frames = (nU x 44.45) - 0.75
Example: 3U = (3 x 44.45) - 0.75 = 132.60
 
Inside Usable Width of Subracks / Card Frames = nT x 5.08
Example: 63T = 63 x 5.08 = 320.04
 
Overall Depth of Subracks / Card Frames = nD x 1
Example: 245D = 245 x 1 = 245
 
All dimensions are in mm
