MEILLER swing doors

Swing doors for industrial and heavy-duty lifts with external door hinges and flap lock

DT 38/2, 3, 4

All panels of the DT38/X landing swing doors are locked using MEILLER’s pressure-proof type-tested MKV flap lock on the transom housing.
Even in this line of doors, it is possible to variably select the frames, transom heights and frame widths.

The two-panel, centre-opening DT38/2 swing door equipped with flap lock is available in a heavy-duty industrial design and as a three-panel DT38/3 version in order to maintain a smaller pivoting range for the door panels in the vestibule with the same permissible dimensions. The door is also available in a four-panel version, the DT38/4, to allow for folding the doors onto the side wall. The DT 38/X door line is also available upon request with oversized door dimensions.
