The folding doors LIBRUM move along a lower guide, meaning that most of its weight is concentrated on the foot of the door and it is not supported by beams or upper lintels. This makes the doors more stable and with a smoother operation, so they are convenient for large spaces, both indoors and outdoors.
When the door is opened, either towards one or both sides, the sheets run along the guide, folding at the end of the movement by means of a deflector that stores the sheets of the door, incorporated in the upper guide.
On the other hand, the lower guide can optionally be reinforced to withstand the traffic of heavy loads. The operation of the door can be manual or automatic with manual cancellation in case of power failure.
The option of a pedestrian door with a lintel and lower skirting board is provided with a handle or a panic push bar.
