Duuri manhole covers provide various significant benefits; load endurance certification and quality control ensure the durability of the products. Water- and gas-proof covers are safe and also enable installation in demanding applications. The fire protection of the DuuriPro covers is proof of 90-minute fire resistance in accordance with the official IBS fire endurance test for, e.g., the BV-F90 cover.

High-quality and durable opening handles, locking mechanisms, springing and corner shape and unambiguous installation instructions also emphasise the user-friendliness and strong quality of our manhole covers.

Inspection and access hatches include manhole covers, wall or ceiling doors and roof or balcony doors.
