What are the dimensions and definitions of the 19 "system?
The outer width dimension of the installation flange (including the mounting bracket) is 482.6 mm (19 "), so it is defined as a 19" system.
Can it be adapted to Schroff's three section guide rail?
It can be adapted to Schroff and HEITEC, and the guide rail for PCB pull-out locking device. The three section guide rail is mainly designed to meet the needs of PCB plug-in boards with different depths. The end of the guide rail is made of plastic material, and the middle section is made of anodized aluminum profiles. The forms of guide rail ends are diverse, meeting various standard requirements.

Do you have any other styles of guide rails?
Yes. When the split panel is not used, the PCB board card can cooperate with the PCB pull-out locking device to achieve PCB pull-out and locking.
