METU Access Door RD with Silicone Gasket and Metal Knobs (up to 200°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 high temperature resistant metal 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.
