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 A2. The high-gloss polished surface provides additional protection and an elegant appearance. This makes the bimini hinge 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

How it works

Locking mechanism with ball-type locking pin: The joint can be locked in various positions. The ball-type locking pin engages securely and holds the convertible top in the desired position.

Grub screws for fixing: The pipes are fixed in the joint with grub screws, which ensures a secure and permanent connection.

High-gloss polished: The polished surface not only looks elegant, but also offers additional corrosion protection.

Assembly and use

The tubes are inserted into the joint and secured with the set screws. The joint then allows the convertible top to be folded down, with the ball-type locking pin engaging in various positions and locking the top in place.

• Insert the tubes - push the convertible top frame into both sides of the joint.
• Secure - Tighten securely with grub screws
• Flaps - Bring the convertible top into the desired position
• Locking mechanism - ball stud automatically engages
