Floor springs

Sophisticated design from the ground up: all-glass doors in parti­cular, but also any other single or double action swing door can be equipped with a GU floor spring in a design-adequate manner. Thanks to ver­sa­tile adjust­ments and installa­tion pos­si­bili­ties, the floor springs are sui­table for many door situa­tions. Hardly noti­ceable, they lend the door an appealing look. With their small installa­tion height and exchangeable pivot axles including axle exten­sions, the floor springs can be used with many kinds of floor structures and floo­rings. There is scope for longitudinal, lateral and vertical adjust­ment between hou­sing and cement case, which facili­tates door assembly. They can also be used with 2-leaf doors, as there are vari­ants with built-in door leaf coordi­nator controlling the clo­sing sequence of active and pas­sive leaf.
