Ronstan Series 30 Ball Bearing Orbit Blocks offer an incredibly high strength-to-weight ratio, achieved through all-composite reinforced polymer materials and multiple attachment options.
The precision design provides the optimum number of ball bearings for minimum friction while weight reduction is achieved through the use of fibre-reinforced composites in the block head, cleat arms and beckets. Suitable for up to 8mm rope
SLH use these for our custom anchor trolley kits because they are the best block we’ve found for the job, in terms of performance, weight, strength and ease of installation. If you were looking to build your own anchor trolley kit these would be a really good choice of block for you to use
