Whether you’re a parent, a caregiver, or a school administrator, protecting children and vulnerable individuals is of the utmost importance. The added security benefits of restrictors are undeniable. Not only do they limit the opening distance of windows, but they also make it much more difficult for intruders to gain access to your property. In addition, installation is a breeze, as window restrictors can easily fit almost any window type, including uPVC, wooden, and composite windows. Plus, with a range of types and designs, you can find the perfect match to suit your needs and requirements.

Cable Window Restrictors:

Cable window restrictors are a highly effective and practical solution to enhance the safety of any property.

In addition to their safety benefits, cable window restrictors also offer a number of advantages in terms of security. By limiting the opening distance of windows, these devices make it more difficult for intruders to gain access to a property, providing an added layer of protection for your home or business. This is especially important in settings where vulnerable individuals are present, such as care homes, hospitals, and schools.

Concealed Window Restrictors:

Concealed window restrictors are an innovative solution to enhance the safety and security of any property, without compromising on the aesthetics of the window. These safety devices are designed to be installed within the window frame or sash, making them invisible to the naked eye. This means that they do not interfere with the visual appearance of the window, providing a clean and minimalist look.

They are also suitable for use on most types of windows, such as uPVC, Timber and Composite. Concealed window Restrictors are both secure and visually beautiful, as they enable you to concentrate on the original design of the window.
