This key-operated cable restrictor is designed to limit window opening on site, balancing the need for ventilation with practical safety considerations. The unit features a 200mm steel cable that restricts the window to a 100mm maximum opening, and is lockable with a key to allow for full access as required.
Supplied with case-hardened, zinc-coated security screws, it is compatible with most window types including uPVC, timber, and aluminium frames. Suitable for use in both domestic and commercial environments, the restrictor is straightforward to install and provides a versatile access solution for new builds, refits, or maintenance work.
