Morten Simoni — Thu, 02 Oct 2025 09:46:52 +0000

The IPP inspection hatch can be used in both ceilings and walls. The inspection hatch ensures easy access to built-in installations / concealed pipework.

The rim is made of high-quality ABS plastic and is suitable for repainting with acrylic and water-based paints or wallpapering.

The inspection clamp can be installed with mortar or glue. It is possible to install the inspection clamp in areas with high humidity. DUKA does not recommend installation in areas where the inspection clamp may be exposed to water splashes, as it is not equipped with rubber gaskets, which means water can get through the cracks.
