Product Overview
Ball bearing blocks deliver high performance and sensitivity for static and dynamic loads. A smooth and efficient block is critical to the conversation between sailor and boat especially for hand-held control lines. Ronstan designed the Series 20 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, UV stable acetal sheave that runs smoothly on a two stage system of low friction bearings. Acetal ball bearings handle moderate loads for high efficiency. As forces increase ball bearings can become distorted; shy of distortion a plain acetal bearing running on a stainless steel race shoulders the load keeping the ball bearings safe from damage while maintaining low friction. 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 subtle messages your boat sends you though the lines by using efficient and smooth Ronstan series 20 blocks. This 20mm triple with becket, shackle and loop top is versatile and can be used for a wide range of applications. Ideal as part of a 6:1 system for backstays, boom vangs, outhauls and more that are not cleated remotely.
