CVMGB500/500/300 - MADE TO ORDER WITHIN 5 WORKING DAYS

Manufactured to order from 0.8mm or 1.0mm galvanised mild steel depending on size. Grille boxes are available with or without a 20mm flange at the open end.

Most grilles require this flange; egg crate, single and double deflection for example are generally always screwed through the front face into the flange on the box. Diffusers however, do not require this flange as the boxes are commonly fixed to the grille through the side of the grille box.

Note: All grille boxes are open at the bottom. All grille boxes will be sized to ensure your grille/louvre will fit inside.
Please scroll down to see various grille box depths.
For rectangular and side entry grille boxes, please call for price/delivery.
