Metal Grille Box 450mm x 450mm - Side Entry 525mm High - 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.

Spigot size must be smaller or equivalent to box size

Note: All grille boxes are open at the bottom.
