Features :

Open frame

  Open frame : The IMRAK Open Frame is available in the standard heights of 27U, 37U 42U and 47U. The non preferred heights of 12U, 17U, 22U and 32U are available.

Side Panels

  Side Panels : Strong, lightweight side panels are easily fitted into position using smooth action slam latches. A centre grommet may be removed and replaced with a lock if required

Plain steel & glass doors

  Plain steel & glass doors : Doors suitable for the front or rear of IMRAK cabinets are available in metal and glass. Shortened doors can also be fitted to provide space above or below for fan units, grills, infill panels or cable entries. Doors incorporate a key-lock mechanisim which can be replaced with swing or electronic locking handles

Perforated and vented doors

  Perforated and vented doors : Perforated doors may be fitted to the front or rear of an IMRAK cabinet and have
an open area of 63%, making them idea for secure applications where front to rear cooling is required. Shortened doors as well as split (wardrobe style) and glass vented doors are also available by special order.

Swing Handl /  Lock

  SWING HANDLE / LOCK : Imrak doors may have a swing handle fitted in place of the factory supplied cam / lock mechanism. Locks must be ordered separately and are available in two versions; Self Locking (where the door automatically locks when closed) or Manual Locking (where a key must be turned to lock the door).

Front cover trims

  Front cover trims : For applications where no doors are required, a set of aluminium trims may be fitted. Cover trims are supplied in pairs painted in RAL 7037 and with an inset green plastic “coach line”. As an option, red or blue coach lines may be specified at extra cost.

Side Vented

Top covers :

  SIDE VENTED : High top side vented – allows air flow through side slots.

Fully Vented

  FULLY VENTED : High top fully vented – allows air flow through a matrix of square top holes as well as side slots. Recommended when fan trays are to be used.

 19” Panel Mounting Angles

  19” Panel Mounting Angles - ‘Standard’ Panel mounts are supplied in pairs to provide 19” mounting positions with hole patterns to accept captive nuts on universal centres. Incorporated into the design of the mounts are notches in the centre of each U height which makes the positioning of the cage nuts much easier.
The panel mounting may be attached directly to the corner vertical, in which case front to rear adjustment is 60mm per panel mount. Alternatively the panel mount may be fitted onto panel mount angle supports giving infinite adjustment throughout the depth of the rack .

Cable Reducing Channels

  Cable Reducing Channels : Cable reducing channels are suitable for 800mm wide racks only. These units are supplied in pairs and may be attached directly to the corner vertical, or fitted onto panel mount angle supports. Reducing cable channels have been designed to support panel mounting angles. The appropriate size and type of panel mounting angles also need to be ordered.

  Castors : Two types of castor are available. All castor loads are stated under average conditions, fitted to the rack bolt on mounting plates. Available in braked and unbraked versions.

Adjustable feet

  Adjustable feet : These allow you to align your rack on uneven surfaces. Adjustable feet are screwed directly into the corner blocks, using 10mm threads. An adaptor is required when feet are to be fitted as well as heavy duty castors. Adjustment is between 25mm and 40mm.

  100 mm plinths : Plinths as complete kits Plinth kits are available in two heights; 100mm or 200mm. Plinth kits consist of four identical corner sections and four infill sections which allow easy modification for cable entry. Adjustable feet, which will align IMRAK on uneven surfaces, can be fitted to a plinth when the use of ‘adjustable foot adaptors’. Plinths may be stacked to provide additional height.

100 mm plinths
100 mm plinths
Bolting down plate

  Bolting down plate : This kit of 4 rectangular plates allows the base frame to be bolted down, using 12 mm bolts (not supplied).

 Bottom gland plates

  Bottom gland plates : Gland plates are used to seal off the cable opening in the base of the rack. Half gland plates allow a cable entry kit to be fitted in the center position. The cable entry kit consists of two brushes through which cables may be pushed.

Top mounted fan trays

  Top mounted fan trays : Top mounted fan trays are available to aid the cooling of your rack housed equipment. These may be retro-fitted to the IMRAK 1400, and occupy none of the useable U height. Fan trays are supplied with four or six fans Top fan trays have blanking plates fitted in all unused positions. Connection to all fans is by means of a CEE 22 mains inlet, which must be ordered separately. Select appropriate mains lead from lower table.

Chassis supports

  Chassis supports : These steel supports may be varied along the depth of the rack and offer an ideal method of supporting heavy equipment. When used in conjunction with 19” equipment they position cardframes accurately in line with U heights. An extra 15mm width is available when chassis supports are fitted directly to panel mounting angle supports as maximum chassis width is then 465mm. Nominal load rating is 50kg. Chassis supports are sold in pairs.

Chassis trays

  Chassis trays : These steel trays come in four depths so that the correct depth for your installation may be selected without interfering with cabling or power distribution at the rear. With this style of tray a pair of chassis supports is also required.

Heavy Duty Shelves

  Heavy Duty Shelves : For applications where heavy loads are required, this shelf offers a load capacityof over 100 Kg. Slotted holes offer limited air passage and also provide simple fixing positions. Note: Must be fitted to two pairs of Chassis Supports.

19” Cantilever Shelves

  19” cantilever shelves : Cantilever shelves fix directly onto the standard 19” panel mounts. The shelves occupy 2U of panel mount height. Cantilever shelves have a nominal load rating of 20kg, mounted in the mddle of the shelf.

Sliding shelves - 19” fixing

  Sliding shelves - 19” fixing : This shelf will fit into the IMRAK® enclosure that has 19” panel mounts fitted in the front and rear of the enclosure, independent of whether the enclosure is 600 mm or 800 mm wide. The supporting surface of the shelf is in-line with the bottom of the ‘U’ above it, therefore the shelf can be used to support both 19” mounted equipment as well as non 19” mounted equipment.

Verak EMC cabinet construction & sealing


Commsrak and Labrak360 are two products based around a common 19” open cabling frame, designed for applications where all round access is required. Both types are available in heights of 12, 37 and 42U with a static load rating of 150kg for all sizes. They are finished in RAL 7035 grey. The verticals feature standard 19” panel mountings with a regular repeating pattern of cable management cut-outs to allow front to rear cabling. The units are supplied in flat pack form with only one type of fixing used throughout


Commsrak is a wall mounting version suited to the IT industry and particularly useful for cable patching. The frame is secured to the wall by four heavy duty brackets that provide a 400mm standoff between wall and 19” panel mount.


Labrak360 is a floor-standing variant aimed at the laboratory / test environment. The minimal design of a frame with a floor standing kit provides unrestricted all-round access to the 19-inch frame, making setup, configuration and testing of the installed equipment a very easy process. The floor standing kit fits within the industry standard 600x600mm footprint and is fitted with castors (braked and un-braked) to make locating it in the required position a simple task.

KM6-HD ( Heavy Duty ) Subracks

The KM6-HD subrack range meets the requirements of IEEE 1101.10 & 11, which expands on IEC60297 to add functionality required for modern industrial computing applications. This includes RFI shielding, a rear transition area, front panel ESD / coding and handles with an injector / extractor operating feature. KM6-HD is therefore well suited to VME64x, CompactPCI applications, serving typical markets such as Telecoms, Medical and Instrumentation. In addition, KM6-HD would suit any rugged application where a resistance to shock and vibration is required.

Built to meet MIL-STD-167, its features include positive guide retention, heavy two screw fixing tiebars, 3mm thick side plates & rack angles and a conductive finish throughout. The KM6-HD subrack accepts standard Eurocards in 3U, 6U & 9U heights and depths of up to 400mm in both the IEC 297 and IEEE1101.10 standards.This makes the card frames suitable for housing popular backplane types such as VMEbus, VXI, VME64 Extensions, VPX, VXS, CompactPC, PXI and also DIN connectors with the use of a connector mounting extrusion.
