Orbit Blocks™ feature advanced polymer technology, ten times stronger than steel, to produce a product that is more compact and lighter, too. Use Orbit Blocks™ for applications including control lines, mainsheet systems, spinnaker sheets, halyards, vangs and backstays for dinghies and small catamarans up to 30-foot keelboats. All Purpose (AP) Blocks are a great all-around solution. For durability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing.
Use Ronstan's Shocks Sheaveless Blocks for small-line rigging applications that do not require ball bearing blocks. Shocks are great for moderate load uses where minimal purchase is required. Snatch Blocks are a tough and reliable solution for temporary leads and line deflection. Simple and quick to deploy, they can be easily opened when the load is released. Lead Blocks are a low-profile solution for leading halyards or other rig sail controls back to cleats or jammers. Utility Blocks are simple, versatile and economical. Their stainless steel cheeks and UV-stablized Acetal sheaves ensure long service life with virtually no maintenance required. Wire Blocks have purpose-designed narrow sheaves and grooves, which make them well-suited for halyard, vang and backstay applications.
