Manual door opening and closing is facilitated significantly by the tension spring assembly. SB rolling shutters and rolling grilles up to 6000 × 4500 mm can be moved with little force. For rolling shutters / rolling grilles with an optional operator, the tension spring assembly reduces wear on the mechanical door elements and operator technology.
Precise matching of the door, operator and control ensure the smooth operation of the rolling shutter / rolling grille. With a complete door solution from a single source, these components form the perfect team. While Hörmann rolling shutters and rolling grilles stand for durability and functional safety, they are also trouble-free to maintain.
As standard with
WA 300 R S4
In combination with a WA 300 R S4 operator, the SB and TGT rolling shutters / rolling grilles are characterised by a high level of safety when opening and closing. Thanks to the standard power limit in the “Open” and “Close” directions, most curtain variants and size ranges do not require the installation of a closing edge safety device to meet the requirements of DIN EN 12453.
Minimum heat loss and gentle door travel
Hörmann classic rolling shutters with the optional ZAK system feature a tighter fit, thereby minimising heat loss. The ZAK system displaces the barrel on the support brackets and precisely guides the door curtain so that it always enters the side guides vertically.
