Telescopic locking system
To meet the needs of every outdoor space and the tastes of those enjoying them, Ermetika® Cristal XL can be equipped with a locking system that allows it to automatically fasten to the side runners. By acting on the tensioning of the canvas, the locking system prevents the closure from rising accidentally by securing it at the desired height. When raising, the terminal automatically unlocks to allow the complete wrapping of the fabric. The insertion of the locking system is at the discretion of the installer because much depends on the terrain and the slope at which Ermetika® Cristal XL is placed.
