Product Description
Ronstan Series 100 Strop Orbit Block, Double
Product Information
Orbit blocks™ are a no-compromise product range developed to meet the demands and expectations of the very dedicated and increasingly professional racing sailor. Side cheeks incorporating head structure and hub are precision machined as a single part from solid alloy, leaving material only where it contributes to the load carrying capacity of the block and eliminating the need for additional fasteners. The Orbit sheave has captive acetal or Torlon® ball bearings for side thrust loads, eliminating the need for side retainer plates. This reduces weight and allows for a wider bearing surface that can accommodate longer Torlon® needles – achieving a substantially higher strength-to-weight ratio.

- The highest strength-to-weight ratio
- Minimal friction loss, especially when working at high loads
- Captive ball bearings for side thrust loads
- Totally reliable and trouble free performance
- Simplicity of design and construction to facilitate maintenance and servicing

Nice, special treat
Every other night my dogs receive a wrapped chicken stick. They look forward to this around 7pm and then start to settle down for the night.

Every dog I’ve ever heard of loves these.
Style: Medium, Size: 10 Chews
The only thing my dog likes better is hooves. These are better by far for dogs.I feel good about the health benefit. This certain one in fact. Pricey but if your dog isn’t big they last a long time. Weeks or a month for my 12# dog. Subscribe and get in bulk. We had a 45# dog (since passed) If you give it to your dog for a period of time then remove it you can make it last longer. NEVER give a smaller one for their weight but you can go bigger. You don’t want choking hazard. I’ve never heard of any dog ever that didn’t want it. They may immediately love it or let it sit a few days wondering but once they start? They’ll guard it and go crazy.
