The SDZ system is an ideal solution for the renovation of existing buildings, when there is a need to replace the old roller shutters with the use of lintel boxes. The design of this system allows for quick and trouble-free installation on existing surfaces. SDZ shutters can be controlled manually with a belt retractor, a crank mechanism, as well as electrically.
