    Description

    DISEC STONE Rok Sferik BD121-25D1 – Anti-Pull Euro Cylinder Protector

    The DISEC STONE Rok Sferik BD121-25D1 is a mechanical security protector for Euro profile cylinder locks, featuring a hemispherical carbonitrided steel body and an anti-pull edge. Designed to resist direct mechanical attacks on the cylinder, it incorporates the reinforced Flex System mounting arrangement and is specified by DISEC as burglary resistance grade 4.

    STONE construction and anti-pull protection

    The hemispherical body reduces accessible gripping surfaces for tools used in forced-entry attempts. The anti-pull edge provides an additional structural feature to resist forces applied when attempting to extract or remove the protector.

    The carbonitrided steel construction protects the cylinder from mechanical attacks while retaining the front key opening. The Flex System uses reinforced fixing screws to improve mounting resistance.

    Compatibility and installation

    The BD121-25D1 is intended for Euro profile cylinder locks with 38 mm fixing centres, including certain CISA and Mottura lock configurations. Actual compatibility depends on the lock model, fixing-hole positions and cylinder projection relative to the external door panel.

    When replacing an existing protector, compare the escutcheon dimensions, protector projection and fixing arrangement. A DISEC cylinder protector spacer is also listed separately in the Matteoda catalogue and may be ordered where suitable, subject to installation compatibility.

    Before ordering: check the 38 mm M6 fixing centres, cylinder projection and protector dimensions. Contact Matteoda customer service for assistance with product selection and estimated delivery times.
