The RONSTAN Series All Purpose Block family provides durable, low-friction performance for a variety of sailboat control line applications. Self-lubricating acetal polymer sheaves running on stainless steel races ensure smooth operation under dynamic and static loads while Grade 316 stainless load housings or straps deliver corrosion-resistant strength. These blocks are designed for low maintenance and long service life, making them suitable for mainsheet, halyard, vang and spinnaker control lines and for leading lines back to cleats or jammers. Built with impact- and UV-resistant reinforced nylon components where used, the Series blocks balance wear resistance and lightweight construction for cruising and racing use.
