19" 30U Rack
The offered product is a telecommunications cabinet in the 19" Rack standard. Its external dimensions are 61 x 183 x 61 cm, consisting of two modules: 12U + 18U (30U total). It features a single-wall, two-chamber construction and is made of steel sheet with a Magnelis coating. In the bottom part, there are 6 holes (38 mm diameter) for cable routing. Inside the cabinet, there are 4 rack rails with a mounting depth of 420 mm.


Freestanding, for Outdoor Use
The cabinet features an IP54 protection rating and is suitable for outdoor use. The design is protected against water and dust ingress. As a freestanding cabinet, it can be appropriately anchored to the ground (e.g., concrete), mounted on a telecommunications manhole, or placed on a pedestal (sold separately).
Solid Doors, Mounting Space for Active Cooling
The manufacturer utilized two pairs of solid doors that open up to 120°. The cabinet does not have any additional removable side panels. In the side parts of the base, there are 4 ventilation holes (144 mm high) providing passive ventilation. Additionally, 4 mounting spots for fans (125 mm diameter) are provided in the upper section—these can be purchased separately if active cooling is required. The doors are secured with a patent lock installed in a swing handle and are locked at three points.
