UK Suppliers Of Sunflex Gearbox Cylinder Module

The Sunflex Gearbox Cylinder Module is a precision-engineered add-on component designed to expand the functionality of your existing bi-fold door hardware. This module is specifically manufactured to connect directly to the Sunflex SF02 primary gearbox, interlocking to form one continuous, high-security locking unit. By integrating this module, you can easily add a Euro profile cylinder locking point to a standard Sunflex bi-fold system, ensuring enhanced security for your folding sliding doors. Ideal for both professional installers and DIY homeowners, this module solves the common issue of needing a modular locking solution for oversized or bespoke door configurations. Because it links physically to the main SF02 unit, it ensures perfectly synchronised operation across the entire height of the door leaf. Whether you are replacing a faulty unit or upgrading a non-locking handle set, this genuine-style Sunflex component provides the structural integrity and smooth mechanical feedback required for premium aluminium door systems.

Features Modular design: Connects directly to the SF02 gearbox to form a single continuous unit Compatible with all standard Euro Profile cylinders Non-handed: Suitable for both left and right-hand opening door leaves Durable zinc-plated steel construction for long-term corrosion resistance Specifically designed for Sunflex bi-folding door profiles Ensures synchronised locking action when linked to the primary gearbox FAQs How does this part connect to my existing gearbox? The module features a connecting interface at the top and bottom that allows it to interlock with the Sunflex SF02 gearbox, creating a single, rigid locking strip that operates in unison. Can I use this module on its own? No, this is an extension module designed to work as part of a modular system. It must be linked to a primary SF02 gearbox to function correctly within a bi-fold door leaf. Does this module come with the Euro cylinder? The module is the housing only. You will need to purchase a standard Euro profile cylinder separately to complete the locking installation. Will this fit any brand of bi-fold door? This component is specifically designed for Sunflex systems. While it shares some visual similarities with other modular locks, it is only guaranteed to fit and link with genuine Sunflex SF02 hardware. Do I need to buy any special tools to link the two gearboxes? No special tools are required; the modules are designed to slot together and are typically secured into the door sash profile using standard fixings.
