The new, versatile Ronstan Shock Block Sheaveless Pulley is only 7/8" long, yet it is very strong, super lightweight, and designed for performance.
We would not recommend these Shock Blocks on foil kites. The pulleys on foil kites move quite a bit more and the bridle line is usually thinner which may wear out faster on the Shock Block.
