• Technical Information

    Important Note: all separate restrictor variants have been tested and proven to comply with the relevant standards when tested on windows in conjunction with variable geometry friction stays produced by Securistyle. Should the products be used with other hinge types, it is the responsibility of the window fabricator or Systems Company to prove their suitability in use and compliance with relevant standards and/or legislation.

    Part codeRestricts the opening to (mm)
    RS4100 or less
    RS680 to 200
    RS9100 to 300

    The actual opening gap achieved will depend on the orientation of the restrictor, the hinges used, the vent size and the window profile design.
