IOU/A, and IPO/A doors are always equipped with an espagnolette lock system and venting hardware. Venting hardware enables the door to be locked in the ventilation position. The door closes and opens by turning the handle. A multi-function espagnolette can be installed at the factory as an option, so the door has a daytime function and the door can also be closed by pushing. As standard IOU/A and IPO/A doors have a Primo 83 handle and an IOU/A door has an interior pulling handle also that is installed at the factory.

The balcony door glass height can be specified according to the height of the adjacent window. A full-glass balcony door is an option also.
