Ronstan 40 Orbit BB Quin Block with Becket & Swivel

The Ronstan Series 40 Orbit BB Quin Block is engineered for optimal performance, integrating strength and reliability in a lightweight design. It features top-tier dynamic and static load ratings among performance blocks of this size. The block's construction includes toughened glass fiber reinforced nylon cheeks, replacing traditional stainless steel straps for enhanced efficiency and reduced weight.

Available in various configurations, including single and double sheave options, this block supports a range of applications from simple setups to advanced 12:1 purchase systems for performance catamarans.

It integrates a carbon-reinforced C-Cleat for efficient rope handling, ensuring low entry and exit friction. The stainless steel cleat arms are adjustable, allowing you to tailor the cleating angle to your preference.

Ball bearing options utilize a 2-stage bearing system designed to minimize friction while providing optimal performance even under heavy loads, whereas High Load versions with 2205 stainless steel sheaves are crafted for high dynamic and static load scenarios, ensuring reliability and low friction in demanding applications.
