GU Lockable Gear Slide Fold Door Multipoint Locks

GU Multipoint Locking Gear for Slide-Fold and Lift-Slide Doors

Slide-fold and lift-slide patio doors require specialized locking hardware that accommodates their unique operation. Unlike standard hinged door multipoint locks, these systems must allow for smooth panel movement while still providing secure multi-point engagement when closed. MPLocks carries GU Ferco lockable gear components designed specifically for these demanding applications, including insertable gearboxes, terrace door locks, tilt-turn assemblies, and heavy-duty sliding door runners. These parts are engineered for aluminum, vinyl, and wood door frames commonly found in European-style patio door systems.

Heavy-Duty Construction for Large Door Panels

Slide-fold and lift-slide doors often feature oversized glass panels that place significant demands on locking hardware. The GU components in this collection are built to handle these requirements, with sliding door runners rated for panels up to 300 pounds. The lift-locking gear accommodates sash heights ranging from approximately 83 inches to over 108 inches, making these parts suitable for expansive patio door installations. High-quality steel construction with ferGUard Silver surface sealing provides long-term corrosion resistance for reliable performance.

Modular Design for Flexible Installation

Many GU slide-fold door components feature modular plug-in designs that simplify installation and replacement. The ALU-JET insertable gearbox, for example, offers tool-free installation and a non-handed design that works for both left and right-hand door applications. Terrace door locks are available as two-part assemblies, allowing you to replace just the upper lock section or lower handle assembly as needed rather than the entire mechanism.

Selecting the Right Backset and PZ Measurement

Choosing the correct replacement part for slide-fold doors requires matching both the backset and PZ (handle height) measurements of your existing hardware. Backsets in this collection range from 25mm to 50mm (approximately 1 to 2 inches), while PZ measurements vary depending on the specific lock configuration. For tilt-turn and tilt-slide applications, pay close attention to the lever rotation specification—some handles operate at 90 degrees while others rotate a full 180 degrees. Measuring your existing hardware before ordering helps ensure proper fit and function.
