Pre trepanned cut outs to include 178mm o.d. ducting on selected chambers.
The square Ids access chambers are now undergoing a transitional phase where 178 mm trepanning as standard is moulded into the chamber. The 300mm2 chamber (MC1) will accept one 178mm duct, the 450mm2 chamber (MC3) will accept one 178mm duct in addition to two 110mm ducts on each side and the 600mm2 chamber (MC5) will accept two 178mm ducts on each side.
If a greater number of duct ports are required then there is the option of stacking the chambers vertically or utilising the Ids medium duty chambers.
