ILCA Pro Quick Release Clew Block

The Pro version of our quick-release clew block assembly combines the Allen 20mm High Load Dynamic Tii-On Block with a 5mm strip shackle featuring a retaining bar.

The upgraded High Load block delivers lower friction than the standard version, improving efficiency under load and offering increased durability for long-term performance. This means smoother outhaul operation and less effort on the water.

The block remains permanently attached to the shackle without compromising overall length or block performance. A stainless retaining bar ensures there is no risk of the block coming free, while still allowing the block to be replaced in the future if required.

The easy-to-use locking shackle can be operated reliably even when wearing gloves, making this Pro assembly an ideal choice for fast, secure, and dependable clew attachment and release.

Top Tip: Squeeze the shackle mouth together to make fastening and undoing the shackle even easier.
