Knockouts for small diameter pipe leads 300mm and smaller can be provided in addition to what is shown.
All dimensions are in millimeters unless otherwise shown
Determine all degrees of separation between each set of pipes.
If an angle measured does not correspond to any of the tables then round down the angle to the nearest corresponding table.
Take each set of pipes and their corresponding angle of separation then compare them to their appropriate table.
The largest size of MH will govern – Table is based on OPSD 701.021 (Nov 2014 Rev #4)
