Square Top Entry Grille Boxes

Ventilation Ducting  | Grille & Plenum Boxes |  Square Top Entry Grille Boxes



Manufactured to order from 0.7mm or 0.9mm 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

Note that all grille boxes are open at the bottom.

Please scroll down to see various grille box depths.

For rectangular and side entry grille boxes, please see the Rectangular & Bespoke Grille Boxes section.
