Experience the ultimate in performance and reliability with the Ronstan Series 40 Orbit Single BB Single Stand-Up Block, a premium choice for sailors and boat enthusiasts alike. This exceptional piece of equipment is designed to provide class-leading dynamic and static load ratings, making it the perfect solution for a wide range of applications, from mainsheet systems and spinnaker sheets on dinghies and off-the-beach catamarans to halyard, vang, and backstay applications on boats up to 9m (30ft).

The secret to the Series 40 Orbit Block's exceptional performance lies in its innovative design, which incorporates lightweight and strong toughened glass fiber reinforced nylon cheeks, replacing traditional stainless steel straps used in utility blocks. This not only reduces weight but also increases strength and reliability, making it the perfect balance of performance and reliability. The block's 2-stage bearing system, featuring ball bearings to minimize friction and a secondary full-contact bearing to maintain low friction across the full working load range, ensures effortless trimming and superior load handling.

The Ronstan Series 40 Orbit Block is also incredibly versatile, with a range of options to suit different needs and preferences. Choose from traditional single swivel blocks, single and double sheave lashing or soft attachment options, or opt for multiple sheave blocks, including those with quad and quin sheaves. Whether you're sailing on a small dinghy or a large yacht, this block is designed to provide exceptional performance and reliability, even in the most demanding conditions.

One of the standout features of the Series 40 Orbit Block is its high-performance cleating system, which ensures secure rope holding with low entry and exit efforts. The carbon-reinforced C-Cleat™ and adjustable cleat arms made from stainless steel allow for customizable cleating angles, giving you total control over your sail trim. The block's fairleads also enable fast action from any angle, making it easy to adjust your sail trim on the fly.

With its impressive specifications, the Ronstan Series 40 Orbit Single BB Single Stand-Up Block is capable of handling heavy loads with ease. The block's sheave diameter of 1-9/16 inches and maximum rope diameter of 3/8 inches make it suitable for a wide range of ropes and applications. Its maximum working load limit of 880 pounds and breaking load limit of 1760 pounds ensure that it can handle even the most demanding conditions, while its lightweight design means it won't weigh you down.

Whether you're a competitive sailor or a recreational boater, the Ronstan Series 40 Orbit Single BB Single Stand-Up Block is an exceptional addition to your sailing setup. With its unparalleled performance, reliability, and versatility, it's the perfect choice for anyone looking to take their sailing experience to the next level.
