Glenelg were approached to provide a design solution to counteract the threat of ‘lock snapping’ in French Doors and Conservatories. Therefore, we developed ‘Patlock’. Recommended by Police Forces and Crime Prevention organisations UK wide, it is a simple and elegant design that provides a strong visual deterrent.


By utilising our contacts in China we facilitated manufacturing of the initial batch of product. Furthermore, the product’s popularity (driven by recognition on national TV shows including ‘Dragons Den’) led to increased customer demand. Consequently, we have also overseen production scale-up to meet this new requirement.


Meanwhile, Glenelg continue to expand the product range. For instance, we have developed ‘Lock Lock’ – a fully patented, integrated solution that eliminates ‘lock snapping’ as a weakness inherent in the design of French Door handles.

When I saw Patlock I immediately saw its potential. Patio doors enhance our homes but can be a boon for burglars, often they are the entrance of choice for thieves. Patlock is not only a police approved product that makes a door harder to break – it is a visible deterrent.
