Ronstan "Orbit" Ball Bearing Block - 40mm - Single / Becket / Swivel Head

Orbit™ Ball Bearing Block - 40mm

Series 40 BB

Kilogram for kilogram of working load, Ball Bearing Orbit Blocks™ are the world's lightest. The unique orbital design allows the bearing to be only in the active areas of the floating sheave. Weight and bulk are further reduced in the different block configurations. The ball bearing single with becket blocks have a through-sheave becket arrangement. The result is the lowest weight possible.

Block RF45110 features a stainless steel, swivel shackle head for unlimited block rotation and ultimate durability. It also has an ultra-low-profile integrated becket.
