The range at a glance
Single door roadside enclosures
Compact GRP cabinets from 340mm wide, designed for life at the kerbside: inbound power supplies, water standpipes, gas installations and feeder pillar duty. Approved patterns used by UK DNOs.
Double door roadside cabinets
Wide, clear access for distribution boards, switchgear and multi-meter installations. Double doors mean you work on the equipment, not around the cabinet.
Wall mounted enclosures
Smaller GRP boxes for fixing to walls, posts and structures where a floor-standing cabinet is overkill.
Floor standing enclosures
Free-standing GRP cabinets for plant rooms, compounds and external installations — a wide spread of sizes between the roadside ranges and the walk-ins. See also our guide to GRP enclosures for distribution boards.
Walk-in enclosures
Full-height GRP kiosks up to 2m × 2m × 2m, including pre-fitted electrical variants — effectively a small building, delivered in one piece and craned onto a prepared base. More on the big end of the range, including bespoke sizes, in very large GRP enclosures.
Why GRP for electrical equipment?
GRP (Glass Reinforced Plastic) is non-conductive, doesn't corrode, and shrugs off UK weather for decades without painting or maintenance. It is light enough to handle without a crane on smaller jobs, yet tough enough for unattended roadside duty. We've covered the full case on our Why use GRP page — and if you're weighing materials, see GRP vs steel enclosures.

IP ratings across the range
Most of the range is rated IP55 or better as standard, with IP65 available on many models as an upgrade. The rating you need depends on exposure: sheltered wall-mounted positions can live with less, while coastal or spray-exposed roadside positions deserve IP65. Every product page lists the rating and links the full drawing/spec sheet.
