The Ronstan Series 50 All Purpose Stand-Up Block delivers high performance and durability for demanding marine applications. Engineered with a self-lubricating Acetal polymer sheave, this block provides exceptionally low friction and extended service life. The construction features a grade 316 stainless steel load strap paired with impact-resistant, fibre-reinforced Nylon cheeks for superior strength. Designed for versatility, the Captive Lock universal head adjusts to two planes or swivels freely to suit specific rigging requirements. This unit includes a saddle and spring, making it ideal for direct 4:1 purchase systems like mainsheets and boom vangs. Its slotted pin shackle design effectively prevents line fouling during operation.
