The Rotoslide V4 model is a variant of the automatic Rotoslide sliding door. These two products are set apart by the different size (height and depth), while passage width remains the same. Just like the basic version, the Rotoslide V4 door also ensures wheelchair access, with an access way that is fully 120 cm wide. The wings move around a sliding pivot (they rotate and translate), so even with the wide passage, the footprint is very small.

The Rotoslide V4 sliding pivot door is multifunctional because it brings together a spacious, practical entry with the functionality of an emergency exit and the security of a SAIMA door. The wings are made out of 12 mm thick laminated glass, while a plastic material was chosen for the side panel, designed with accident prevention in mind, that protects the wings themselves. As in every automatic SAIMA access way, door opening sensors are installed, as well as safety photocells both on the interior and exterior
