Currently there are doors and windows sliding type safe enough to be compared with the opening or folding type. This is due to embedded multipoint locking in some series aluminum frame. Previously closures were installed with a sliding trigger-point, which in many cases are easily unlockable from the outside. Unlike multipoint locking, which can anchor up to three locations, and provides the enclosure of an unprecedented security in the world of the woodwork today. Keep in mind that we are talking about the type doors and sliding windows, more expensive than the type lifting or tilt-parallel, which already incorporate similar systems, in this case the money is extremely more competitive. One such series that supports multipoint lock is the series S-76 and S-76 RPT, apart from having a great capacity for large glass thicknesses and weights, the strength of it and the money best on the market makes it highly recommended for both doors and windows. As we see in the first image, in PONSICO s.c.p. add a handle on the main road lumen and embedded in the outer end, in order to cross comfortably leaves for cleaning and maintenance.
