Lightweight
Kilogram for kilogram of workload, the Orbit BB and RT blocks are the lightest in the world. The unique orbital design allows the bearing to be located only in the active areas of the floating pulley. This minimizes the mass of the inactive return ring and the hub.

Weight and bulk are further reduced in the different block configurations. The single and becket ball bearing block features a through-pulley becket arrangement. The result? The lowest possible weight.

Multi-sheave pulleys have only one intermediate cheek and an ultra-light and efficient head arrangement. This gives a 30% weight saving advantage over the nearest competitor. Othersbrands simply connect their individual blocks. This results in unnecessary double cheeks between each pulley, held together by a heavy steel channel running through the top of the block.

Highest working load in its class
Orbital ball bearing arrangement provides the largest possible bearing ring diameter. This maximizes charging performance. The proven Ronstan 2-stage bearing system features high compression grade acetal ball bearings and a full contact secondary bearing. This gives minimum friction across the entire working load range.

The floating pulley and bearing system is supported by a fiber reinforced load frame. The design was computer modeled to optimize constraints. The Dyneema Link is produced from FSE Robline SK75 fiber, which is 10 times stronger and lighter than steel, and provides the final connection of theblock at the load point.
