What size is a Standard Size GRP Enclosure


What size is a Standard Size GRP Enclosure” is a question we get asked many times, and to be honest it’s a difficult one to answer as it depends on its intended use.

Adept GRP try to cover all eventualities by offering a significant range of standard sizes, these Range from our VR1 Cabinet which is suitable for a small distribution board and a double socket through to our VR20,  a much larger Enclosure designed to operate as a Switchgear Housing. The Roadside Range in between these two examples are intended to offer variations in the hope that there’s always a GRP Cabinet or GRP Housing to suit everyone. We do come across instances where floor space is limited and the tight restrictions mean that a GRP Kiosk of a particular size is specified, we can overcome this by designing and manufacturing an Enclosure to fit into the available space. We have even had instances where the space was so restricted there was no scope for the Enclosure doors to be opened, we overcame this by fitting a small roller shutter door which, whilst providing the necessary security, also provided full access to the equipment inside, allowing for essential maintenance as and when necessary.

To summarise, GRP Electrical Enclosures and Large GRP Housings can be manufactured by Adept GRP to suit your particular application, Doors, Vents etc can be positioned to suit and we are able to manufacture in most external colours from the BS or RAL Range. Please visit our online store to view our Standard Range of Electrical Cabinets, Large GRP Enclosures and Bespoke GRP Kiosks.

The company’s application for SafeContractor accreditation was driven by the need for a uniform standard across the business. SafeContractor accreditation will enhance the company’s ability to win new contracts, and its commitment to safety will be viewed positively by its insurers when the company liability policy is up for renewal.

Gemma Archibald, Director of Alcumus SafeContractor said: “Major organisations simply cannot afford to run the risk of employing contractors who are not able to prove that they have sound health and safety policies in place.”

“More companies need to understand the importance of adopting good risk management in the way that Adept GRP Enclosures has done. The firm’s high standard has set an example which hopefully will be followed by other companies within the sector. SafeContractor plays a vital role in supporting our clients in meeting their compliance needs, whilst working with their contractors as they progress through the accreditation process.”

Adepts Dan Phillips echoed the positive sentiments adding “We’re naturally pleased to have been awarded our Safety Accreditation for another year, the importance of Safety both on and off Site is of paramount importance to us and something we continually strive to improve”
