INSTALL YOUR GATES
Our automatic blast gates have been specifically designed to fit 100mm and 150mm A/NZ standard PVC stormwater pipe. If you need them to fit other ducting, then this is possible but will incur a delay as we modify our CNC machining program to suit.
When you are designing your layout please note that a gate that is fixed to a structure can support up to 1200mm of ducting on both sides. However, if the ducting is supporting the gate then we recommend a separate support back to a solid structure within 1200mm of the gate.
The gates have been specifically designed to fit in 1 branch of a stormwater Y junction as below...
