We stock used weatherproof GRP enclosures in standard and non-standard sizes ideal for transformers and switchgear
If you are looking for a cost effective and efficient way to keep your electrical equipment protected from the elements, we have a selection of GRP enclosures for you to choose from.
These used floor-standing glass reinforced plastic enclosures are readily available and can be sold as seen or refurbished to a high standard, ensuring integrity and reliability, providing peace of mind that your equipment will be safely protected by a robust weatherproof enclosure.
We have a selection of different configurations and sizes available including double doors on one or both sides, standard and non-standard sizes with blast roofs and ventilation louvres. Battery Tripping Units, lighting and 230V electrical packs can be fitted on request.
