More about the WM4 GRP enclosure:
The WM4 is a wall-mounting GRP enclosure measuring 330mm wide, 200mm deep and 430mm high. It is moulded in one piece from glass-reinforced polyester with a smooth gel-coat finish, finished in grey RAL 7035 as standard, and sealed to IP66 with an IK10 impact rating — built to live outdoors and take a knock.
What is the WM4 used for?
At 330x200x430mm it suits single and sub-meters, instrumentation and telemetry or RTU outstations, CCTV and communications nodes, small control and relay gear, cable terminations and marshalling, and irrigation or pump-status panels. Because GRP is naturally non-conductive it removes any touch-voltage risk, which makes the WM4 a sound choice on footways, forecourts and other public or wet locations as well as inside plant rooms.
How does it stand up outdoors?
GRP doesn’t rust, rot or corrode, and it shrugs off UV, rain, frost and salt air with very little maintenance — which is why GRP enclosures are a standard pick for coastal, water, rail and process-plant sites where a steel box would be rusting within a season. The IK10 shell resists impact and the material carries no scrap value, so it’s of no interest to metal thieves.
How does the WM4 lock and open?
Its door is hung on stainless-steel hinges, seals on a one-piece polyurethane gasket and carries a built-in rain canopy; it can be re-hung either side simply by turning it over and opens right back to 120° (180° with the door lifted off) for easy access. It is secured with twin double-bit (3 mm) cam locks as standard, with a stainless padlock hasp available where a site needs keyed-alike or padlocked access.
How is it mounted and fitted out?
The WM4 fixes to a wall on four external brackets, clear of the sealed area so the enclosure stays weather-tight, and a pole-mount kit is available where there’s no wall to use. An internal mounting plate (galvanised steel, polyester or insulating grade) drops onto the fixing studs and is specified separately so you get the right backplate for the gear going in.
What colours and sizes does it come in?
Grey RAL 7035 as standard, with green (BS 14-C-39) or any British Standard or RAL colour on request. The WM4 is 330x200x430mm; browse the full wall-mounted range for other sizes, or our floor-standing enclosures for larger plant.
