The Orbit ball bearing is unique.
The proven Two-Step bearing system allows minimal friction under load.
The Dyneema® Link is 10 times stronger than stainless steel and can be attached straight (0°) or crosswise (90°).
Cheeks, cleat arms and cleats are made from reinforced plastic.
Double and triple blocks are manufactured without double side plates, making them narrower and lighter than conventional blocks.
