NEW - ISC Rigging Pulleys Released for Sale

Recommended Posts



Early 2010 saw the start of a major project by ISC to modernise a timeless classic. The ISC Cast Pulleys are probably the most widely used Pulley Blocks by Arborist's for rigging around the World.

Originally developed in 1996 these blocks have been the backbone to most arborist's rigging situations and a tool every arborist both young and old has come to trust and respect.


Like all classics there finally comes a time to make some changes.

During the re-development of the pulley it was important to retain its classic features but introduce change.

The new rounder profile enhances the whole tactile feel of the block and reduces the risk of burred or sharp edges that may wear a rigging rope.



What's New

Increased radius on all edges both internal and external

All pulley details are now easily located on an Identification Plate

The internal Spring Lock location hole is now honed out for easier location

Increased internal width to accommodate larger diameter anchor slings

Larger diameter top & bottom axles; Diameter increased by >10%

What's Retained

The classic ISC Pulley Block Shape

The trusted and proven Spring Lock System eliminating chance of cross threading

Same external dimensions (Length & Width)

Same strengths as the previous versions

CE certification to European Machinery Directive


Currently available in two models

IS-RP051-A1 SRP £89.00+vat

IS-RP055-A1 £109.00+vat

These can now be ordered and purchased from all good Arborist Supply Retailers


ISC is a SPONSOR of the "ultimate arb competition" and these will be part of the prize fund.
