Sheerline Reveals Ingenious Partnership Behind Bespoke High-Security Locking System

West Midlands-based Ingenious Locks & Hardware (Ingenious) has become the latest company to partner with Sheerline. The manufacturer of high-security multi-point locks and hardware developed a bespoke system tailored to the newly launched Index™ Bi-Folding Door system.

The partnership saw the respective R&D teams working closely to ensure the one-of-a-kind system met both Sheerline’s and its customers’ needs. This includes in-built, cleverly designed security features, which are an integral part of both company’s products.

That’s why the new system offers five hook multi-point locking with DUPLEX hook units, a spring assisted centre case for lever applications, and all locks are extendible with connectors to take M8 threaded high security shoot bolts.

As with every multi-point lock developed by Ingenious, this system meets rigorous industry specifications including PAS24 and Secured by Design (the official police-backed initiative).

In line with Ingenious’ ten year ‘fit and forget’ guarantee, operation and compression is smooth for ease of use over the product lifecycle. Keeps are also high security and suitable as standard for double door applications.

The fully symmetrical one-piece keeps are designed to accept a concealed flip-over lever, driving shoot bolts to the head and threshold. This clever design has turned a simple keep into a French passive lock and saved on a set of handles.

These added security features are another way to enable Sheerline’s innovative Index™ Bi-Folding Door system to stand out. Launched in August 2024, the product was developed to help installers maintain their competitive advantage against cheap imports lacking in quality.

Adrian Redshaw, Sheerline’s Product Design Director, commented: “This partnership reflects Sheerline’s commitment to in-built security as standard across the entire product range. It has been a great opportunity working with the Ingenious team to develop a unique system specifically for our Index™ Bi-fold customers.”

“Supporting British manufacturing is part of being a proud British manufacturer, and this partnership highlights the fact we’re open to collaborating with like-minded companies across the UK who share our values for innovative, high-quality, and stylish yet practical solutions that provide tangible benefits for all our customers,” he added.
