The Antal 150mm Composite Fibre Block features an aluminum sheave on composite fibre
bearings and double self-captive Delrin ball thrust bearings.
The sides are made of 3571 TA16 light alloy and are thickly anodized to
ensure absolute wear-and corrosion proofing, with all the edges smoothed
off for better handling. Nuts and bolts have been replaced with recessed screws and pins,
considerably reducing weight and eliminating any projecting parts, and the steel coupling revolves on a fibre washer and can easily be locked
in one of two main positions.
