Cinch Adapter for DIR Harness (3mm / 6mm Plates)

Stainless steel adapter pin with rubber shims for quick adjustment of shoulder straps on technical backplates.

The Tecline Cinch Adapter, available at DIR-STORE, is the perfect accessory for those who want the benefits of an adjustable harness without sacrificing the safety and clean design of a continuous, single-piece webbing (DIR standard). This ingenious stainless steel sliding system allows for instantaneous widening or tightening of the shoulder straps, greatly facilitating donning and doffing of equipment, especially when using thick drysuits or bulky undersuits.

Key Features and Benefits:

• Quick Adjustment: Allows the harness webbing to slide smoothly through the backplate slot when lifted, then securely lock into position once tensioned, maintaining the system's geometric stability during the dive.
• Total Adaptability (Dual-Thickness Kit): The pin comes complete with special soft, molded rubber washers/shims. This modular system allows the adapter to be configured for both standard 3mm backplates and heavy 6mm backplates, always ensuring ideal sliding space for the 50mm webbing.
• Marine Grade Stainless Steel Construction: Made entirely of high-quality stainless steel, resistant to tension, impact, and prolonged corrosive action in marine environments.
• Simple and Clean Installation: It mounts directly to the lower slots of the backplate quickly and intuitively, without requiring structural modifications to the backplate or cutting the webbing.

Why buy the Cinch adapter?

• Maximum wearability without failure points: It allows you to don and doff your twinset or single tank with maximum ease, eliminating the need for quick-release plastic buckles, which represent a critical failure point.
• Perfect for those who change wetsuits throughout the year: If you switch from a summer wetsuit to a winter drysuit with a heavy undersuit, you can adjust the shoulder straps to the millimeter in seconds right in the field.
• Maintains a minimalist harness (DIR Geometry): Offers the convenience of an adjustable recreational BCD but retains the hydrodynamic, clean, and uncluttered profile typical of technical diving.
• Universal "All-in-One" solution: Thanks to the shims included in the package, you don't have to worry about the type of backplate you own: it instantly adapts to both lightweight 3mm and heavy 6mm backplates.
  

Technical note: The installation of this adapter does not require any permanent modification to your equipment and preserves the integrity of standard 50mm (2-inch) webbing.
