New model large-capacity, plastic roof collector. Produced in two varieties – the first is all plastic and the second is a combination of plastic with a cast-iron upper surface. The structure of the roof collector is reinforced with ribbing, which ensures greater strength and stability of the product in the ground. Also included is a dry, anti-odour flap to prevent backup odours from the sewer pipe. The new hinged-lid system is simpler, in order to give easy access to the removable filter basket, preventing dirt from spreading. Triple protective partition against seepage, dirt collection basket in plastic or stainless steel – made to order.
