External Electrical Enclosures – RB Range

The RB range of external electrical enclosures were initially developed with the street lighting and highways industries; however, their highly flexible, modular design means they are suitable as enclosures for protecting electrical and/or electronic equipment in the most inhospitable external environments (fabricated from 4003 grade stainless steel as standard).

Features and Benefits

  • Stainless steel external enclosures
  • Options include shelves, racking, lights, environmental control etc for the protection of electrical and electronic equipment
  • Standard range stocked or we can manufacture to your specified dimensions

Alternative sizes

As we manufacture our stainless steel enclosures ourselves, we can easily adapt our cabinet designs to whatever dimensions you need.  Please give us a ring or drop us a line if you want to discuss custom sizes.

External electrical enclosures internal accessory kits

The other new feature of the RB Cabinet is that the internal, modular design permits the fitting of a range of extra equipment, from shelves and partitions to climate control equipment etc.  This means that cabinets with extra features don’t have to be specially made – reducing lead times and cost.

The kits can be supplied loose, pre-installed, or ordered and retrofitted at a later date.

  • Shelf kit (inc. mounting brackets and required number of shelves).
  • 11 “ or 19” rack unit.
  • Partition.
  • Glanding bars.
  • Cooling fan kit.
  • Louvre filter kit (recommended with fan, to prevent dust).
  • Heater kit.
  • Internal light kit (LED light including door-activated switch).

Block hinges are often needed by the highways industry for their extra strength, to make door removal easier and for >180 degree opening.  To address these requirements we developed a new hinge system which had all of these benefits, but without the unsightly cut outs in the door and/or body of the cabinet.

We believe that the door: body interface on our RB cabinets adds even more to the superior appearance of our stainless steel enclosures.  And this is without any functional compromise, as the mechanical properties of the cabinets have been improved too.

The RB Cabinets can be supplied with a detachable plinth which is installed in the ground before fastening the enclosures down. Alternatively, these external electrical enclosures can be fixed down to any hard, flat surface, without the plinth.
