By using the 19″-DIN rail support 3 U, cap rail enclosures can be mounted recessed onto the 19″-frame. Due to its solid and partially closed structural form the 19″-DIN rail support offers a high level of protection and is well suited for the fixation of small cases that contain electronics. An integrated cable catch with strain relief on the back ensures a well structured cable management. The front panel, which can be obtained optionally, serves as protection against contact and allows a closure on all sides.
