METU Access Door RD with Silicon Gasket and Plastic Knobs (up to +80°C)
Sturdy, press-formed METU access door for rectangular ducts or flat surfaces made of an inner and an outer cover plate which are pulled together thanks to two bolts and corrosion-resistant knobs. In doing so the duct wall is clamped evenly between the two access door covers. A silicon (SI) profile-ring wrapped around the edge of the inner cover makes the access door air-tight even by higher pressures. The oval shape of the access door allows an easy installation into the opening.
