compactMaster CMR and CMR-F curved sliding door

Rounded out – sliding door with a revolving appearance

A curved sliding door unites the attractive appearance of a cylindrical door system with the benefits of an easily accessible sliding door. Whether in the form of a segmental arch, a semicircle, or a full circle up to a diameter of 4000 mm, the compactMaster CMR / CMR-F curved sliding door integrates perfectly into the architecture of a building. Through the use of sophisticated profiles (G30 profile system), extensive transparency is combined with comprehensive functionality. For escape and rescue routes, the CMR-F version offers broad opening widths up to 2500 mm. The drives are certified to DIN 18650/EN 16005 and type-tested by TÜV and comply with the current directives and standards. The CMR-F drive system is tested and suitable for use in escape and rescue routes (AutSchR).
In the CMR RC3 and CMR-F RC3 versions, the curved sliding doors are tested in accordance with EN 1627 to ensure they are burglar-inhibiting.
