When there is only few space or not space at all to the side, the sliding hatch EFA-HVS® CR is used which opens and closes vertically. The door leaf closes flush with the guides and closes hermetically. Typical areas of use of the EFA-HVS CR are logistics, materials-handling technology as well as material and lift shafts in controlled zones. The door leaf of the hermetic vertical sliding hatch is also available as stainless steel finish, as option.

The fixed door leaf which is made of single-walled transparent laths is kept in a certain distance during winding up. Thus, the EFA-STT of the CR series remains transparent for many years - also for door sizes of 4x5 metres!
