Hörmann Truedor ISEO Lock

Hörmann Truedor has further strengthened the security credentials of its composite door range with the introduction of the new ISEO R700 S3 High Security Cylinder, now supplied as a standard feature across the range at no additional cost. Forming part of Hörmann Truedor's ongoing commitment to product development, the new ISEO cylinder ensures installers and homeowners benefit from the latest advances in door security.

Engineered to provide outstanding protection against today's most common methods of forced entry, the ISEO R700 S3 features a patented locking mechanism and has been independently tested to rigorous UK security standards. It has achieved TS007 3 Star certification and Secure Diamond accreditation, giving installers and homeowners confidence that the cylinder meets the highest recognised levels of domestic door security.

The cylinder incorporates a range of advanced security features, including anti-snap technology with sacrificial sections and an internal protection mechanism that helps maintain the security of the door even if the cylinder is subjected to a snapping attack. Additional anti-drill protection is provided through hardened drill-resistant components, while resistance to specialist attack methods is enhanced with Ice Attack Protection. A tungsten carbide cam assembly further improves both durability and security.

Designed with ease of use as well as security in mind, the ISEO R700 S3 benefits from precision engineering and tight manufacturing tolerances, delivering smooth, reliable operation throughout its service life. The cylinder is available in both key/key and thumb turn configurations to suit a wide range of residential applications.

The addition of the ISEO R700 S3 High Security Cylinder to the Hörmann Truedor range provides installers with an even stronger proposition, combining attractive door designs with market-leading levels of security, long-term reliability and added value for homeowners.
