The new, versatile, sheaveless Shock Block by Ronstan is only 7/8" long, yet it is very strong, super lightweight and designed for performance.
*Pro Tip - Always check pulleys for wear and tear and replace when needed. A broken or jammed pulley can ruin a kite bridle.
Would not recommend on foil kites. The pulleys on foil kites move quite a bit more and the bridle line is usually thinner which digs into the block.
