Product Overview
General application blocks provide performance and value. A smooth and efficient block is critical to the conversation between sailor and boat especially for hand-held control lines. Ronstan designed the Series 50 All-Purpose blocks to give dinghy and small keelboat sailors the feedback to detect subtle wind changes and sail as efficiently as possible. These light-weight blocks feature a durable, self-lubricating, UV stable acetal sheave that runs smoothly on a 316 stainless steel bearing. Fiber reinforced nylon cheeks provide rigidity and strength and are beefed up 316 stainless steel load straps. The included shackle features a pin with a low-profile head to prevent snagging on smaller lines. Get the messages your boat sends you though the lines by using efficient and smooth Ronstan Series 50 All-Purpose blocks. This 50mm single with shackle head is versatile and can be used for a wide range of applications. Great for halyard tuners, Cunninghams, dinghy sheets and more.
