Fully forged in High Resistance stainless steel, the MX offers one of the
best available strength/weight ratios. Compared to standard blocks and for the
same line diameter, the MX offers much higher working and breaking loads as well
as optimized dimensions and weight. The MX requires no specific lashing
knowledge. Its installation is as easy as installing a shackle, thanks to its
self-locking pin.
