Roof inlet gravity DrainBox DN110 vertical, with PVC collar HL63P/1

Efficient roof drainage with gravity downspout DrainBox DN110

This vertical roof inlet, made of high-quality materials, is a reliable solution for gravity drainage of roofs. Its construction, based on corrugated sheet metal, ensures durability and resistance to atmospheric conditions. The housing with adjustable height (100-160mm) allows adaptation to the specifics of the roof and the thickness of the insulation.

The DrainBox DN110 inlet is compatible with water drainage systems with a diameter of DN110, using spigot or compensating socket connections with welded HDPE. It provides an efficient water flow – up to 5.82 l/s – which guarantees effective drainage of rainwater even during heavy rainfall.

Construction and installation – solidity and ease of installation

The inlet is equipped with a PVC collar, which facilitates a tight connection with the roofing membrane. The solid construction and the possibility of adjusting the housing height translate into easy and quick installation. This solution is appreciated by both professional installers and people independently undertaking renovation works. Thanks to this, the installation process runs smoothly and without problems.
