Single-door GRP cabinets
CR4 GRP cabinet
A wide single-door cabinet with a modest 400mm depth. Built to order in Wales for panels that need width and height more than they need a deep body.


900mm wide, without a deep footprint
The CR4 gives you 900mm of width and 1295mm clear internal height, with depth held at 400mm. It is for wide, relatively shallow panels, or sites where the cabinet cannot stand far off a wall or fence line.
If the gear is deeper than 400mm, the CR5 keeps this width and adds 135mm of depth. If 750mm of width is enough, the CR3 is the smaller step.
Need two doors for fitting out a wide panel? Look at the double-door range.
