Extra low treshold

The way of casing of the door with an extra low threshold and a usual threshold is except the first section identical. The door with an extra low threshold can be therefore executed with the same accessories available for a standard passage door (panic fittings, panic lock, fix handle instead
of a door handle etc.)

A passage door with an extra low threshold can be used for both the manually operated sectional garage doors and doors with an operator. The operator must be executed with a control of contact with an obstacle, e.g. detection of labour force. For a sectional industrial door the extra low threshold can be used on doors manually operated and on doors with Totmann control.

The extra low threshold of a passage door is provided by an overhang edge from both sides.
