The SJB is ZPAS’s compact 19″ network cabinet for offices and businesses: a self-supporting sheet steel body without a frame, full glass door made of safety glass, three heights (12/15/18 U), degree of protection IP 20 — optionally with a design worktop as a fully fledged piece of office furniture.
Small, sturdy, stylish — network technology in office format
Not every network needs a server room. Patch panel, switch, router and a small UPS fit into the SJB on 12 to 18 rack units — lockable behind a full glass door made of safety glass, tidy thanks to cable openings with brush strips. The self-supporting body without a frame makes it light and compact; in RAL 7035 (light grey) or RAL 9005 (black) it blends into any environment. When a compact network cabinet is enough and when it has to be a floor-standing cabinet is explained in the server rack guide.

Design worktop: the network cabinet as a piece of furniture
As an accessory, an 18 mm thick laminated MDF worktop turns the SJB into a storage and work surface — in three decors: Calvados (wood look), black and light grey. Important for the climate inside the cabinet: the raising kit mounts the worktop with a 19 mm clearance above the roof plate. This improves passive ventilation — and is absolutely essential when a fan is used in the cabinet, so that the exhaust air can escape.
Standard equipment from the factory
Accessories: from the castor set to the socket strip
Available separately: design worktop and raising kit, castors instead of levelling feet, equipment shelves and drawers, fans (only with the worktop raising kit), socket strips, earthing bar, additional brush strips and a cross member on the rear panel for cable strain relief. This way the SJB grows with your needs — from a simple patch cabinet to a small technical hub.

Frequently asked questions — SJB
Who is the SJB intended for?
For small networks in offices and businesses: patch panel, switch, router, small NAS — where a floor-standing cabinet would be oversized. Lockable, discreet look, optionally with a worktop as a piece of furniture.
Which sizes are available?
Three heights: 12 U (604 mm), 15 U (737 mm), 18 U (871 mm) — width 600 mm, depth 600 or 800 mm (12 U only in depth 600). Usable depth max. 560/760 mm.
What is the design worktop?
An 18 mm MDF board in Calvados, black or light grey for the roof plate. With the raising kit (19 mm clearance) it improves ventilation — when a fan is used, the raising kit is mandatory.
Can the SJB be made mobile?
Yes, with a castor set (accessory). Four levelling feet are standard. Equipment shelves, drawers, fans, socket strips and more are also available.
