METU Access Door RD with NBR Gasket (up to 80°C) - Liquid-tight Version
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. An NBR gasket fitted around the edge of the inner cover makes the access door liquid-tight. The oval shape of the access door allows an easy installation into the opening.
