Product Updates: TRIPODS

Product Updates: TRIPODS

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.

It's here...the NEW D5 Work/Rescue Descender!

March 21st 2016

The D5 Descender has been designed for use on 1/2" (12.7mm) rope. The D5 is compliant with NFPA G and Z359.4:2013 and developed for the North American Fire & Rescue and Tower Climbing markets, which typically use 1/2" ropes.

 The D5 is a double-stop device with an auto-lock function, which is activated whenever the operator releases the handle; and a panic-brake function, which is not overly sensitive in normal use. The D5 also has a double-locking safety mechanism.  In addition to the locking button, the side plates are designed such that the plates cannot be rotated open, whilst under load, due to the position of the Karabniner.  

The D5 is easy to attach/detach from the rope, without having to detach from the harness, therefore eliminating the risk of accidental dropping of the device. The D5 features a progressive cam action, which offers precise control during low or high speeds.  The cam is made from high grade, solid Stainless Steel, for maximum durability, even in harsh environments, such as Geotech work.

A unique feature of the D5 Work/Rescue Descender is that the handle rotates through 360 degrees and emits audible 'clicks' as an indicator to the user of positive engagement of the mechanism.   It is also easy to back-feed the rope through the D5 and therefore the D5 can be used for smooth ascending or for emergency hauling (when used as part of a 'Z-rig').

The D5 has a Working Load Limit of (500lbs) 240kg, making it suitable for two-man rescue situations, without the need for the creation of extra friction.

Product Update- Forged Rigging Pulley

February 5th 2016

The small and medium versions are now manufactured using Hot Forged Technology, combined with high quality materials and components.  These blocks are rope friendly, durable and extremely robust.  These features combined give maximum security and strength, when the block is rigged as part of an impact system.

Apart from the aesthetically pleasing curves, the ISC impact pulley is designed to work (together with textiles) to absorb the huge forces which are created by the harsh dynamics of heavy Arborist work.  The side plates are produced using the best quality hot forged Aluminium and the special manufacturing process allows these pulleys to offer a highly impressive strength to weight ratio.
