The FIBRAIN SRS-33-6/8-S04-B is a 33U floor-standing network cabinet from the FIBRAIN DATA range, 600 mm wide and 800 mm deep, finished in black RAL 9005. It is designed for indoor installations such as server rooms, telecom rooms and building distributors, and can be combined with neighbouring cabinets into rows or a Data Box arrangement.

The front door combines a glass panel with metal sides and is closed by a three-point rod-latch lock with swing handle; it opens up to 180° and its opening direction can be changed. At the rear, a shortened solid steel door with single-point lock is complemented by a 3U panel with a brush strip below it for cable entry. Solid steel side panels have single-point locks, and two pairs of 19-inch mounting profiles with U marking carry the equipment.

Top and bottom plates feature 71 mm wide cable openings, wide enough for a power cable with a three-phase plug, all closed by knock-out blanking plates. The cabinet can stand directly on the floor with no protruding elements underneath, and on levelling feet it achieves IP20 to EN 60529 (excluding brush entries). FIBRAIN rates it for 1000 kg of equipment on levelling feet or a plinth; an earthing bar and earthing cables are included.
