The Ronstan Series 15 Ball Bearing Triple 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.

• The sheave is precisely-molded, UV-stabilized acetal running on stainless steel ball bearings, so it delivers high performance with low friction
• Cheeks, head post, shackle, and ball bearings are all 316-grade stainless steel for maximum corrosion resistance in saltwater sailing
