Product Overview
The Ronstan Series 15 Ball Bearing Single Block is a tiny, light and versatile block with a 5/8" diameter sheave and a very high breaking load. Ronstan's Series 15 Ball Bearing Utility Blocks are the tiniest ball bearing blocks anywhere, running on sheaves only 5/8" (15 mm) in diameter. They're so light, strong and inexpensive that you can use them in lots of creative applications, like shock cord retractors for your control lines, purchase systems for your foiling Moth, or outfitting your kid's El Toro, Sabot or Opti. Use them for cunninghams, vangs and tweakers, or even for non-boating applications.
