Folding door FE "Teckentrup 50"

Folding door FE "Teckentrup 50"


Folding doors are commonly installed in very wide hall openings up to 16 meters, but also wherever spatial relationships are constrained inside or around the lintel. The Teckentrup FE "Teckentrup 50" folding door offers maximum security and reliability. The high levels of stability also enable use in areas subject to high winds, e.g. in mountainous and coastal regions.
