Our insulated Thermo Boxes come flat packed for ease of transit and storage on site.
Easily assembled by folding into shape and securing with a square SQ2 bit using the screws supplied, fixed into the pre-drilled holes.
The boxes come with pre-score knock-outs (125mm, 160mm and 200mm) that can be removed as required.   The ducting spigot (by others) is then fixed to the outside of the box using suitable tech screws and/or sealant.
