RAS is a popular type of adaptation roller shutter system that features an inspection hatch bent at an 45-degree angle. The hatch is opened from the outside, from the front of the box. The RAS variant allows large-size roller shutters to be made and comes in six different heights. The box - due to the opening inspection hatch, which cannot be plastered over - will be visible from the outside. The RAS variant can be fitted with a rolling mosquito net. The shutter drive is possible in three different positions, depending on the type of installation.
