Introducing the Gatemaster Superhinge Inline version, designed for conventional metal gate installations where the gate and post need to remain aligned, allowing gates to open up to 180°.

Superhinge Inline version is a heavy-duty gate hinge which incorporates brass bearings for smooth, low-friction operation, delivering reliable, long-lasting performance for both manual and automated gates.

• Exceptional Durability: Tested to 500,000 openings without signs of wear, which is equivalent to approx. 50 years of use at 25 openings a day.
• Heavy Load Capacity: Designed to support metal gates weighing up to 600kg, making it suitable for demanding gate applications.
• Inline Hinge Positioning: The hinge pivot sits in line with the gate and post, providing a clean, straightforward installation for conventional gate layouts.
• 180° Opening: Allows gates to open up to 180° where the surrounding gate design permits.

The Gatemaster Superhinge Inline version combines exceptional durability with a practical hinge arrangement for general access, perimeter and pedestrian gates. Designed for long-term performance, it provides a reliable solution for fabricators looking for a heavy-duty hinge suited to conventional metal gate installations.

Maximum gate mass depends on the G dimension, a smaller G dimension generally supports more weight. Refer to the table for the recommended maximum gate mass (table and diagram below).

Introducing the Gatemaster Superhinge Offset version, a heavy-duty gate hinge designed for metal gate installations, allowing gates to open up to 180° back towards the fence line.

Built to withstand demanding use, the Superhinge features integrated brass bearings, to provide smooth, low-friction operation for both manual and automated gate systems.

• Exceptional Durability: Rigorously tested to 500,000 openings without signs of wear (equivalent to approx. 50 years of use at 25 openings a day).
• Heavy Load Capacity: Engineered to support substantial weight of metal gates up to 600kg, and available in various sizes to accommodate different gate sizes and weight.
• Flexible Gate Positioning: The offset hinge arrangement provides greater freedom when positioning gates, accommodating back-hung installations and additional clearance requirements.
• 180° Opening: Designed to accommodate opening angles of use to 180°, allowing gates to open back towards the fence line where the installation permits.

The Gatemaster Superhinge Offset version combines proven durability with greater flexibility in gate design. Ideal for back-hung installations and applications requiring additional clearance, it helps fabricators consider opening angles and potential trapping points while maintaining the strength and reliability of the Superhinge range.

The Gatemaster Superhinge with Corner Lugs is a heavy-duty weld-on gate hinge designed for strength, durability and reliable performance on metal gates.

With corner lugs that weld directly to the gate post, it provides a secure mounting arrangement for demanding gate installations. Tested to 500,000 openings with minimal wear, the Superhinge incorporates the same low-friction brass bearing design and exceptional load capacity, combining robust engineering with a practical installation option.

This makes it ideal for large industrial and automated gates where precision and durability are essential.

• Exceptional Durability: Tested to 500,000 openings without any signs of wear, equating to approximately 50 years of daily use at 25 gate opening per day.
• Heavy Load Capacity: Available in 4 sizes, supporting metal gates weighing up to 900kg per pair of hinges.

• Corner Lug Mounting: Features weld-on corner lugs designed to attach securely to the gate post, providing a robust mounting arrangement for metal gate installations.

• Adjustable Installation: Features an adjustable threaded bolt for accurate positioning and alignment during on-site fitting.
