Access doors for rectangular ductwork pressed from galvanised steel in a sturdy double-shell design with a flow-optimised inner shell to prevent turbulences. Two star-shaped hand knobs with embedded metal threat allow to fix the access panels to the duct. A polyethylene foam gasket securely seals the access panels, so they are suitable for sealing class D (TÜV-Nord certified). Available in sizes from 180x80mm to 700x500mm. Each access door delivered in a bag including self-adhesive drilling plate. Access doors made of stainless steel or with edge protection also available.
