ISC Compact Rigging Block Size:Default The unicender is inherently safer

The unicender is inherently safer than the use of separate ascender and descender devices because there is no dangerous change over at the top of the climb

Replacing the friction plate and cam together will have your lockjack back to performing like new

Ideal as a prusik tending pulley and handy for light rigging and hauling systems

The large diameter offers a considerable contact surface with the rope

ISC Compact Rigging Block Size:Default The unicender is inherently saferThe Lowdown At approximately half the size of the standard small rigging block and weighing in at only 490g (1lb), the new compact rigging block offers a highly impressive strength to weight ratio, with an 85kN (19000lbs) MBS and WLL of 17kN (3800lbs). The Pulley plates are made from hot forged Aluminium and it is this manufacturing process which allows such a compact pulley to boast such great strength and dynamic load bearing capacity. Tech Specs
