The new, versatile Ronstan Shock Block Sheaveless Pulley XL is only 1 7/16" 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.

Features:

• Ultra lightweight anodized aluminum at only 0.42 ounces!
• Compact, durable, and impact resistant
• Color coded:  Red, blue,
• Small line optimized
