Material advantages of stainless steel A4 (AISI 316)

Stainless steel A4 (also known as AISI 316 or V4A) contains molybdenum and therefore offers significantly higher corrosion resistance than standard stainless steel. This makes the convertible top center section particularly suitable for:

• Continuous saltwater contact
• Aggressive marine environments
• Long-term outdoor applications without maintenance
• Professional boat and yacht equipment
• Areas with frequent movement and stress

Toggle quick-release fastener

Tool-free operation: The toggle quick-release fastener allows for quick opening and closing of the hinge without tools. Simply turn the toggle and the canopy folds down.

Hinged nose bolt: The 6 mm diameter bolt ensures secure locking in the closed position.

Time-saving: Ideal for convertible tops that need to be frequently installed and removed - significantly faster than screw connections.

Assembly and use

The tubes are inserted into both parts of the joint and secured. The toggle quick-release fastener connects the two parts and allows the convertible top to be folded quickly. To open it, the toggle is turned and released.

• Insert the tubes - slide the convertible top frame into both joint parts.
• Securing - safely fastening pipes
• Connect - close the toggle quick-release fastener
• Flaps - The convertible top can now be opened and closed quickly.
