Access doors for spiral tubes / round ductwork with edge protection - GRD

Access doors for round 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 thread allow to fix the access panels to the duct. Access doors with self-adhesive edge protection for secure assembly and service. Suitable for sealing class C and D.

Available in sizes from 180x80mm to 500x400mm and for tube diameters from 80mm up to 1800mm.
