19" partial front panels only use a number of the 84 horizontal pitch units (HP) available on a 19 "rack .
Their width is equivalent to a corresponding number of HP < 84 (5.08 mm) minus a certain amount (0.34 mm). The height of the 19" partial front panel is a multiple of the rack unit U (44.45 mm) minus a certain amount (4.95 mm).
The system holes for partial front panels in "Front Panel Designer" take into consideration
|•||the mounting options on the enclosure|
|•||the options for assembling handles and PCB holders|
The system-specific dimensions of the manufacturers Schroff and Fischer are used as a basis.
