The second stage is the Rollet assembly itself, and their further installation in a pre -prepared opening. It is worth noting that the garage roll gates are currently quite in demand. Every day, all new garages are equipped with such gates, which is not at all surprising. Rollet -type gates have undeniable advantages. Firstly, this is a significant saving of free space near the garage and inside it. Based on its design, the gates of this type actually do not require space, since only the protection box is located above the opening. Meanwhile, the process of making a gate of this type is regularly improved, when using new developments and the introduction of modern technologies. In particular, today the defense box can be installed not only over the opening itself, but also in the inside of the room, or even hide the opening. This state of affairs not only provides the external aesthetics of the gate, but also their quality and reliability. For a robber, access to a box covering the drive, as well as roller locks, is virtually impossible.
