The RT inspection doors act as air-tight closures to maintenance openings. The RT inspection door is available in aluminium, primed steel, galvanised steel and stainless steel. It can open to the left or right and have one or two leaves. In addition there are many options, e.g. inspection glass, square lock, KABA lock cylinder, removable central bar, integrated ventilation grating etc. The inspection doors made of stainless steel in high-temperature design are heat-resistant up to 600°C.
Inspection doors are installed wherever access must be guaranteed for maintenance and inspection. They are fitted to close off maintenance access openings to ventilation systems, filter chambers, air conditioning systems etc. The RT inspection door is designed as a standard fitting in ducts and can optionally be supplemented with steel straps for installation in walls.
