The Allen 30mm Extreme High Load Dynamic Blocks with Kicker Key features a custom body designed specifically for Laser/ ILCA vang use. This innovative design eliminates the need for shackles or rope and includes XHL Bearing Technology for exceptional performance under high loads. World-class rigging specialist Max Hunt from Southeast Sailboats highly recommends this block for its smooth operation and strong key, which can handle the increased loads of the Laser MkII rig. Other benefits include a compact size, CNC machined aluminium side cheeks, and a 1000Kg breaking load.
