Rope Wrench Inspection Notice

October 18th 2016

If you own an ISC Rope Wrench, please read this notice carefully.

Reason for issuing this inspection notice

It has been brought to our attention that a number of units are exhibiting a fault which makes it difficult to remove the screw which holds the tether in place. This is not a safety critical fault, but we appreciate the inconvenience it can cause.  ISC want to ensure that our customer experience, when using our products, is reliable.

Reported problem

A number of users have managed to ‘round’ the head of the Allen screw making it impossible to remove.


During our investigation we have found that this appears to be limited to forged frame Rope Wrenches. The affected batches are between 16/71522/xx – 16/77313/xx. In order to ascertain if your Rope Wrench is affected, you need to do a very quick check:

  •  Using a 4mm Allen key remove the Allen screw.

If the screw cannot be removed from the device easily then your device will need to be returned to ISC (via your distributor) – we will supply you with a replacement item, free of charge.


From our investigation we have determined that the holes on some forged frames do not align correctly. This is due to the cranking operation, combined with the variation in thickness of the forged frames.

All current Rope Wrenches manufactured from 5th August 2016 (16/77314/xx) are machined and not forged, therefore should not be affected.

Product Update: NEW RAD Device, with optional Swing-cheek function!

September 28th 2016

NEW RAD Device, with optional Swing-cheek function!

The latest model RAD (RP815.2) now features optional swing-cheek function.  The new top bollard on the '.2' version allows the user the choice of fixing the side plate in place (in line with Lanyard-related standards), or removing the captivation screw, allowing the front plate to be swung open, as required.  The swinging side plate function is particularly useful when the device is used in descent applications.

To convert the device from fixed to swing plate function, the user simply needs to remove the screw from the bollard, using a 2.5mm Allen Key.  A small, flat-head screwdriver is then used to insert a small, headless Grub Screw in to the bollard.  The purpose of the Grub Screw is to keep the threaded hold free from dirt and debris.  This means that the device can then be converted back to 'fixed' function, as required.

NEW HaulerBiner Compact Rescue Kit- AVAILABLE NOW!

September 26th 2016

Extensive market research over the last few years led us to believe that most of the compact pulley systems on the market had failings.  After a long development and consultation period, we believe that the HaulerBiner addresses all of those failings. Prototype samples have been extensively trialled throughout the Rope Access, Tower Climbing and Industrial Rescue sectors and feedback incorporated into the design. It was essential that the HaulerBiner be lightweight, compact, efficient, simple to use/deploy, be fully rated for lifting people and of course be competitive with other systems.

The HaulerBiner is a mechanical advantage system, which has three pulley wheels incorporated into each Karabiner, creating a compact and lightweight 6:1 or 7:1 Mechanical Advantage system.  The HaulerBiner has a purpose designed progress capture cam, with an ‘on/off’ position. 

The HaulerBiner utilises purpose-developed 6mm (1/4") diameter rope, for strength and easy handling/best grip. 

The HaulerBiner can be used in a number of ways:

As part of a pick-off system

On a structure, pull down on the system and achieve a 6:1 (theoretical) Mechanical Advantage

When suspended in a harness, the user can pull up on the system and achieve a 7:1(theoretical) Mechanical Advantage

With a D4/D2 Descender, as part of a short-haul/long-lower system

As a tensioning system for short/low load lines

As a stretcher management device, using two or more HaulerBiners to easily change or adjust the orientation of the stretcher

The HaulerBiner is supplied in a double pocket pouch, for easy deployment and storage on the user’s harness.

The HaulerBiner is available in three standard lengths:

HB105: 105cm (3'7")

HB165: 165cm (5'5")

HB300: 300cm (9'10")

Bespoke lengths available on request.

Global Fire Partnership, Bosnian Fire Project

September 5th 2016

The Global Fire & Rescue Partnership was set up in June 2016 with the sole aim of 'bridging the gap' between nations, in regards to training and equipment. Chris Kendall, Co-Director, set this project up on his return from Bosnia, having seen the inconsistencies of training and equipment across different areas.

The Global Fire & Rescue Partnership is currently a 'not for profit' organisation but is going through the application process for charity status within Scotland.  The organisation is predominantly based in Scotland, but has members from all across the UK. The partnership is solely volunteer run; mostly by serving professional fire service instructors.

The Global Fire & Rescue Partnership aims to achieve their goal of bridging the gap by approaching organisations and quality equipment manufacturing companies and asking for either new or surplus equipment.  They then provide this to those most in need, on behalf of the donor.  

Their main, current project is a unique concept for Bosnia. This is to create, train and equip a dedicated team of volunteer firefighters to the same level of a UK 'Technical Rescue' team. This team will have specialised firefighters trained in Rope Rescue, Water Rescue and Powerboat operations. This is a very in depth project requiring many hours of telephone conversations, emails, instant messages etc. "The Bosnians are very old fashioned in how they look at the fire service there. They cannot look outside of their own town. If one town has two brand new shiny fire engines and only need one, and the next town over has nothing; the first town won't give them a fire engine. What's theirs is theirs, regardless!" said Chris.  "I'm trying to work with various individuals to bring this town/region/municipality in line with that of the UK Fire Service framework and in the hope this will spread".  

Chris has provided the relevant Mayor within Bosnia a 3 year plan of his intentions, which will see a two week training camp taking place each year.  The plans also include a development program for one of their firefighters Kenan Mulalić,  to develop up to instructor level by the end of 2018.  This training will take place at Outreach Rescue (Technical Rescue and Industrial Safety Training organisation), in North Wales, (dependent on Visa applications).

We are delighted to provide a range of ISC Kit, in support of the efforts of Chris's team at Global Fire & Rescue Partnership.  Adam (Product Technician/Demonstrator) and Iain (UK Sales Manager) enjoyed a day out with Chris Kendall and Neil Pickersgill (Manchester FRS), for a product demonstration session, held at a quarry near Manchester. As a result of the trials, we are donating D4 Work/Rescue Descenders, RAD (Rope Adjustment Device)s, RED Back up Devices, Hand Ascenders and a range of Karabiners.  This kit will give the Bosnian team several full cliff rescue kits, suitable for 2 person rescues, complete with back-up.  In October the Bosnian Technicians will come over to the Outreach Training Centre in North Wales, for a series of training courses to bring them up to speed on the UK methods of rescue.  We're also looking forward to welcoming the Bosnian Technicians to the ISC Factory tosee the manufacturing processes of their new ISC equipment!

ISC at the Emergency Services Show 2016

August 30th 2016

This year, for the first time, we will be exhibiting on an outdoor stand (OS55), in addition to our usual indoor stand (G79). 

On the outdoor stand, we will be joined by members of Hampshire Fire & Rescue Team, who will be demonstrating the Arachnipod Total Edge Management System, in some of its nine possible configurations!

On the outdoor stand, there will also be a 9m tower, courtesy of Checkmate Lifting & Safety UK.  This year, visitors to the ISC stand will see live demonstrations of the range of Work/Rescue Descenders, Back-up Devices and Harnesses.  Team Members from HART Training (a division of Checkmate UK) and team members from Leicester Fire & Rescue, will be performing a range of descent and rescue demonstrations on the tower, at intervals throughout the show.

We’re delighted to have Hampshire & Leicester FRS Team Members on our stand, to demonstrate and to share their first-hand operational experience of the products.  For the first time, we will also be able to offer visitors the opportunity to descend the tower, to try out our Work/Rescue Descenders and the Checkmate Vantage Harness.

ISC will also be launching the NEW HaulerBiner Rescue Kit, (a 6:1 / 7:1 compact hauling kit, with progress capture) and a brand new new series of 40, 50 and 70kN Rigging Plates, at the show.

Places on the tower will be limited, but you can book a descent slot in advance, by contacting us at

Product Updates: TRIPODS

May 19th 2016

Following the recent re-testing of our Tripods, we are pleased to announce the following upgrades to our range...

Removal of Webbing Strap

Foot restraint straps have long been a cause for concern in risk assessments because of the potential trip hazard.  We recently requested that our UK Notified Body retest our Tripods, to confirm their strength and suitability without the webbing restraint strap.  The testing found that the strap makes no difference to the performance of the Tripod.  In the future therefore, we will not supply the Tripod with the restraint Strap as standard.


New Markings Plate

All ISC Tripods are now fitted with a durable Anodised Aluminium markings plate/  The markings include a QR Code, which can be scanned (using a Smartphone*) in order to access an electronic User Instruction Manual.  All Tripods are individually serial marked as follows:

YY/BBBBB/XX       Y= Year  B= Batch   X= Unique Reference Number

* App download required

New Max Leg Extension Indicator & Leg Holes

Each Tripod is now fitted with a durable label on the outer face of each leg, to alert the user when they have extended the leg beyond the maximum extension setting.  When the STOP label is exposed, the user should lower the leg setting to the next available hole setting, ensuring that the STOP label is not visible.

The Tripod leg hole spacing and telescopic hole alignment has also been changed, making the Tripod compatible with a range of two-pin accessory brackets, which can now be mounted in numerous positions on the leg.


The WLL of our Tripods has increased from 3500kg MBS (350kg WLL) to 3600kg MBS (360kg WLL), [10:1 Safety Factor]. Our Tripods now meet the requirements of NFPA [G], in addition to EN795 Type B, 1997.
