0,00  with VATPL

SKU: FIREBOX Category:


  • A universal solution designed for indoor installation;
  • For ICT and telecommunications applications;
  • To provide a high degree of protection for network equipment, automation;
  • For mounting 19″ devices.

Design description


  • Indoor, free-standing or wall-mounted on a pedestal;
  • Skeletal, made of a steel frame sheathed in steel or aluminum sheets (joining by welding and bolted connections);
  • Powder coating in any color (RAL) and surface texture with high resistance to deterioration;
  • Combined with a plinth;
  • Polyurethane foam seals;
  • Degree of protection up to IP 55;
  • Mechanical resistance: up to IK 08-10.

The design of the enclosure allows multiple enclosures to be connected in series.

Frame – steel frame

  • Made of steel profiles joined by welding;
  • Has a hole for attaching vertical mounting profiles or other fixtures.

Side covers

  • Mounted to the frame with allen key screw connections;
  • The thickness of the sheet metal adapted to the dimensions;
  • When the side covers are installed, the width dimension of the housing does not change.


  • Solid or transparent;
  • Single-sided or double-sided (back cover), for better access to the apparatus;
  • Single-leaf or double-leaf;
  • Locked with a cylinder lock (any shape) or a basquil lock locked with a system cylinder and an additional padlock;
  • Three-point locking;
  • Internal hinges;
  • Opening angle 120 deg;
  • Grounding studs with wiring.


  • Made of a height-adjustable cover for additional ventilation;
  • The cover has an additional hole, with grommets, to allow the introduction of wiring from cable routes.


  • Has an opening with a cable grommet to allow cables to enter from the cable duct;
  • Prepared for mounting the pedestal with screw connections.


Dimensions adapted to the type, amount of equipment and individual needs of the customer.
Typical implementations:

  • height: 800-2200 mm;
  • width: 650 mm;
  • depth: 400/600/800/1000 mm.


Equipment is selected each time according to the needs of the customer.

  • Vertical mounting profiles, steel, hole-mounted to the frame;
  • Fixed or pull-out shelves, mounted to vertical mounting profiles;
  • rama wewnętrzna uchylna 19’’ – symetryczna lub asymetryczna;
  • Internal frame tilting 19” – symmetrical or asymmetrical;and heating – heating circuits, thermostat together with heating resistor located in the lower part of the cabinet. Lighting – two fluorescent lamps, assembled in the upper part, thanks to which we get an even intensity of lighting across the width;
  • Ventilation – allowing constant airflow through the use of a fan and proper opening of the housing.


plinth – Welded, made in solid or vented versions of any height.
