KT282 Rope Wrench SRT Kit - EN383-2 Compliant

April 24th 2018

KT282 Rope Wrench SRT Kit - EN383-2 Compliant

We're delighted to announce the return of Rope Wrench SRT to the German market.

We recently carried out a full re-evaluation of the Rope Wrench system, following a request by a German Insurance Organisation and the German Market Surveillance Organisation. That re-evaluation has allowed us to improve our overall offering including our test data and user instruction manuals.


In Germany these organisations manage and control insurance issues for Working Arborists. They offered us critical feedback on our Rope Wrench system, which we took very seriously. After a number of positive discussions and meetings we have implemented their recommendations which were primarily:
1. To provide further test data for the entire system, according to relevant European Standards, in order to prove that it is ‘fit for purpose:
We have had several combinations of components independently tested at CE Test Laboratory, SATRA.  Tests were carried out according to EN353-2 ‘Personal protective equipment against falls from a height. Guided type fall arresters including a flexible anchor line'. 

These three combinations passed all of the tests:

1.  ISC Standard Kit

2.  STEIN Kit

3. Courant Kit

2. To further develop our user instruction manuals:
We have updated our user manual to include the relevant test data and combined several manuals into one document, which is available in a printed format and as a download in various languages. 

 The above kits are now fully CE Compliant.  The ISC Standard kit is the first to launch, with advance orders now being accepted, for delivery in June.

RP282 Phlotich Hitch-minding Pulley

April 24th 2018

We're delighted to introduce our new Phlotich Hitch-minding Pulley, a new multi-aperture device specifically designed for SRT and DdRT Climbing systems.  The Phlotich is available in a range of colours, with a choice of Bushings or Bearings.

Phlotich Features & Benefits

Profiled side plates capture the host line, allowing for a reduction in host line movement

Sideplates mate perfectly parallel allowing for a 'clean' connection to the anchoring Karbiners.  The mated sideplates also allow for seamless use of a 'Twin Leg' Tether in SRT climbing with a Rope Wrench.  This reduces clutter and allows proper alignment of the hitch, pulley and tether on the anchoring Karabiner (in a Rope Wrench set up)

Lower anchor aperture will allow for full Karabiner rotation

Dual Karabiner Alignment- when used with Doubled Rope Climbing, the Phlotich allows the two anchoring Karabiners to be aligned efficiently on one pulley, instead of separating to two separate anchors

Unique 'Kidney' aperture:

  • allows for a wide variety of Karabiner connector shapes and will allow rotation of any Karabiner (including ANSI gate). 
  • allows for multiple Karabiner connections at one time
  • allows for a Karabiner to 'centre' itself depending on where the load is applied- and allows Karabiners to 'self centre' during climbing manoeuvers, which is helpful with DdRT climbing when climbing up to a 'large limb'
  • allows for a perfect spot to anchor a 'Sternal' anchoring device (Karabiner, hook, Chestie, etc.) for use in SRT climbing on ascent with a Rope Wrench.  This connector in the 'Kidney' aperture will self align to the most efficient spot and can be removed and attached easily
  • allow the efficient use of the Pulley as a 'trolley' and allows for self alignment of an anchoring Karabiner in the 'Kidney' aperture when used in this configuration.
  • The Phlotich can be used effectively for 'Double Crotching' or setting up efficient mechanical advantage systems due to the multiple attachment points and the ability for multiple Karabiners anchored in the 'Kidney' aperture.

ISC ZipWorld VELOCITY 2 Trolleys launch!

March 22nd 2018

Zip World has opened the doors to its new VELOCITY 2 ride!  Satisfying the public’s growing appetite for adrenaline-fuelled experiences, Zip World aims to put even bigger smiles on more faces, with four new low-noise lines,  with riders reaching speeds of up to 125mph!

To achieve this, ISC has worked closely with Zip World to design and manufacture a trolley that is capable of performing at such incredible speeds, whilst suspended 500ft in the air. The trolley has to be capable of repeating this feat over and over, as demand is expected to be high.

From the outset Zip World wanted to tackle the issue of sound emissions, taking a pro-active approach to reducing the noise generated from its zip lines and considering the effect on local residents and wildlife. Noise reducing systems play a pivotal role, when looking to grow the number of zip lines at any one location, as the more lines in operation, the more sound produced. We relished the challenge and set about the task of developing  the means of making the ZipWorld Velocity 2 Trolleys run near silent, whist maintaining the key design features which make it such a successful and integral part of Zip World’s offering.

The solution was to utilise a unique Polyurethane (PU) “tyre”, which is fitted to the Stainless Steel wheels of the trolley. This additional element to the wheel, replaced the “steel on steel” principle (the main sound contributing factor) of the standard model. We also modified the trolley casing, crafting carefully shaped and positioned holes, allowing sound to dissipate, without being amplified by the side plates of the trolley.

These modifications have meant a reduction in sound emissions of 15dB, resulting in the successful application to open more Zip lines at the Zip World Velocity 2 site!

D4PRO Work/Rescue Descender

March 21st 2018

Feedback gathered from highly qualified and experienced 'Pro' users highlighted a demand for a D4 Work/Rescue Descender device which does not incorporate a panic-brake function.  Enter the D4PRO!  The D4PRO Descender is the same great Work/Rescue Descender, but without the panic brake

This can be particularly useful on longer descents and in rescue/belay applications, where a broader 'sweet spot' is welcomed.

As the D4PRO does not incorporate a panic-brake, it is not possible for the device to fully meet the criteria of ANSI Standards.  The D4PRO is fully certified to EN 12841 and meets NFPA 1983 (a panic brake is not a compulsory criteria of these standards).
If you require a Descender which fully meets ANSI standards, please see

 * 09 April, 2018: Please see updated 'KH260 Inspection Notice UPDATE 09/04/18' pdf*

We have received notice of a very small number of instances of KH260 karabiners where the retaining pin on the nut for the swivel assembly has become dislodged resulting in the nut backing off the stem and the swivel assembly separating from the karabiner. There are no reported injuries associated with this issue, but out of an abundance of caution we wanted to notify potential users of this issue.

Upon initial review, it is limited to a batch of KH260 Twister Karabiner. However, we feel that it is prudent for us to broaden the inspection to include all karabiners that utilize the same assembly method (KH260, KH260i, SH826, SH826i). It has been determined that with careful inspection, karabiners with the issue can be identified in the field.

CE Marked to EN795:2012 (Type E):  The latest and most stringent EN Standard for Anchors.

PD CEN/TS 16415:  Advisory standard - Recommendations for use of anchor points by more than one person simultaneously (fully rated for two person rescue loads).

IRATA International Code of Practice (ICOP) Compliant: Meets the 15kN static load testing, making them the only ICOP compliant Deadweight Anchors available on the market.

The new DW200.2 model also features a new, longer arm and now offers horizontal parapet clearance of up to 350mm (14"). 

 All testing of ISC Deadweight Anchors has been carried out by an
