ASSEMBLY

The panels and roof of the GRP4 Enclosures are bolted together internally, each joint being weather sealed.

Enclosures can be delivered ready assembled, whilst larger ones will be erected on site, normally by ourselves or if access is difficult.

All assembly and fixing screws, nuts, etc., are of stainless steel.

Typical layout of a GRP4 Modular Enclosure

Internal dimensions – 2440mm long x 1830mm wide.
With single door, double door, backing board and lourved vent.
Sited on a concrete base with a raised slab.

INSTALLATION 

The preferred fixing is to use a rebated edge to concrete base and screed over the gap after fixing down.


The alternative fixing is onto a kerb using skirting as detailed.

In both instances, the base must be smooth, flat and level. The base should be 200mm larger than the internal dimensions of the enclosure.



The enclosure is secured down internally with stainless steel coach screws and plastic plugs.
