Types of Window Locks

Window Espags (Espagnolettes)

Espags secure UPVC windows by engaging locking points along the frame, ensuring effective sealing, security, and smooth operation. Duffells stocks a variety of espag lengths and backsets, accommodating diverse window designs.

Window Gearboxes

Gearboxes are central to window multipoint locking systems, converting handle movement into locking engagement. Available from trusted brands, our gearboxes offer reliable replacements for worn or damaged window locks.

Sash Jammers

Sash jammers add an extra layer of security to UPVC and timber windows. Quick to install, these devices effectively prevent forced entry attempts by reinforcing weak points on windows.

Window Restrictors & Cable Restrictors

Restrictors allow windows to be safely opened to a limited degree, reducing the risk of accidental falls or unauthorised entry, making them essential for homes, schools, and commercial premises.

Sash Window Security Devices

Specifically designed to enhance traditional style sash windows, these security locks and stops secure windows effectively against intrusion and provide controlled ventilation.
