Access door for rectangular ducts.
This inspection hatch is designed to provide easy access to the ducts of the ventilation system. Through this hatch it is possible to easily inspect and clean the ducts. The rubber on the plates ensures that this hatch falls under airtightness class D.
The hatch is easy to assemble due to the supplied cutting template and the rotating knobs. The system works with two plates. To mount it, the inner plate must first be placed in the duct. Then the gap can be made airtight by holding the outer plate against the inner plate and tighten it with the rotary knobs.
