Polyethylene siphon gully pots are manufactured using a rotomoulding process.
Two rectangular-section models with differing storage capacities are available and are ready for corrugated polyethylene or PVC pipe coupling at the outlet.
There is also an option of having flame-retardant gully pots – these are manufactured from a self-extinguishing material with a flammability rating of V2 in compliance with UL94.
