The access door is also used as an inspection hatch for rectangular ducts. To the access door belongs a fixing frame,
which is attached to the rectangular duct. This is normally
done with blind rivets through the folded-down edge of the
done frame. It can also be provided with folding tabs on
request.
It is easy to remove the access door from the fixing frame by
using over-centre catches. In the insulated versions, the
inner side will always be in level with the innermost boundary line of the duct, irrespective of whether the duct is insulated internally or externally. The table below shows the
insulation thickness of the door at different duct insulation
alternatives.
