ISC is delighted to launch a new range of swivel karabiners under the brand name 'TWISTER'. The first is the KH255 all-aluminium swivel soon to be followed by a load indicating version and then later by all-steel versions.

It is fully CE approved and also ANSI/CSA compliant.

This karabiner (body and eye) is made from forged aluminium and features an MBS of 25kN/5500lbs. At 138g/4.8oz it is probably the strongest lightest product available in the world. It offers the standard range of gates screwgate, 2-way twistlock, and 3-way supersafe and a gate opening from 16mm/5/8” depending on the model.

As demand for lightweight fall arrest blocks has increased, we found that a good way to decrease their weight even further is by fitting a lightweight karabiner and this is one of the main reasons why the product was developed. There is an indicating version (especially for fall arrestors) and a non-indicating version for general use such as Arborist fliplines.

The karabiner will be available in ISC standard colours – body graphite grey and gates colour coded by type. However aluminium is relatively easy to customise to suit individual branding and as always company logos can be laser etched at a minimal additional cost.
