To gain peak performance, we engineered out the heavy steel load straps, head post, shackle and cleating accessories. Through extensive research and development, we replaced virtually all metal components with high-tech polymers and fibre equivalents.\u003cbr minmax_bound=\"true\"\u003e\u003cbr\u003eWeight and bulk are further reduced in the different block configurations. The ball bearing single and becket block has a through-sheave becket arrangement. The result? The lowest weight possible.\u003cbr minmax_bound=\"true\"\u003e\u003cbr\u003eMulti-sheave blocks have only single intermediate cheeks and an ultra-light and efficient head arrangement. Other brands just link together their single blocks with a heavy steel channel across the top of the block, with unnecessary extra cheeks adding extra weight and bulk not found in Ronstan Orbit Blocks™.\u003cbr minmax_bound=\"true\"\u003e\u003cbr minmax_bound=\"true\"\u003e\u003cstrong minmax_bound=\"true\"\u003eHighest working load in its class\u003c\/strong\u003e\u003cbr minmax_bound=\"true\"\u003e\u003cbr\u003eThe proven Ronstan 2-stage bearing system (Series 30 and larger) features high compression grade Acetal ball bearings and a secondary full-contact bearing.

The Dyneema® Link, used in multi-sheave blocks, is produced from high spec SK75 fibre, which is 10 times stronger and lighter than steel, and provides the final connection from the block to the load point.\u003cbr minmax_bound=\"true\"\u003e\u003cbr minmax_bound=\"true\"\u003e\u003cstrong minmax_bound=\"true\"\u003eSimple, versatile and secure attachment\u003c\/strong\u003e\u003cbr minmax_bound=\"true\"\u003e\u003cbr\u003eThe single block is easily lashed to an attachment point, and can also accept Dyneema® Links and shackles for a variety of efficient attachment alternatives.
