Product Information
Orbit blocks™ are a no-compromise product range developed to meet the demands and expectation 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 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.
Head posts of swivel blocks can be locked at 0 or 90 degrees.
Applications
Primary mainsheet, halyard and spinnaker systems on boats to 14m (46ft)
Secondary mainsheet, vang blocks on boats to 15m (50ft)
Standard and running backstay systems on boats to 12m (40ft)
General control line and lead block applications on larger yachts
Materials
Fully machined Alloy cheek plates
Alloy sheaves with captive ball races
Torlon® needle rollers
Carbon black Acetal ball bearings
Forged grade 17-4PH stainless steel shackles
Grade 316 stainless steel head post

Comfortable
Size: 9, Color: Black/Ivory
Most comfortable and roomy shoes I ever wore. Great for insoles. Looks nice too. The base of the shoe is a bit too thick but it’s fine.

Best purchase ever
This watch is my daily driver. It offers all the bells and whistle for a price point that anyone can work hard and obtain. I do have a wild collection (wild to me. Near 200k in combined value) I can’t count the number of times someone’s asked me hey that’s a cool looking watch or is the the AP on rubber strap. In both instances people are shocked that you can get so much quality at this price point.
