At approximately half the size of the standard small rigging block and weighing in at only 490g (1 lb.), the new compact rigging block offers a highly impressive strength to weight ratio, with an 85kN (19,000 lbs.) MBS and WLL of 17kN (3800 lbs).
The pulley plates are made from hot forged aluminum and it is this manufacturing process which allows such a compact pulley to boast such great strength and dynamic load bearing capacity.
The pulley is fitted with a spring-lock closure mechanism which allows direct connection to rigging slings. This mini-block is designed for 1/2" (13mm) rope and the top sheave will accept 5/8" rope which can be used to attach a falsecrotch lanyard or whoopie sling.
FEATURES:
• Single progress capture pulley
& bull; Compatible with 10 - 13 mm rope
• Bushed, standard free running wheel
• Meets CE EN 12278, EN567, NFPA 1983.
This pulley features a new lightweight center plate, re-positioned wheel to reduce rope friction and a rated becket, through which most carabiners can be fully rotated. The RP703 is fitted with tamper-proof rivets and is individually serial numbered.
Works exceptionally well with the Portable Winch.
The Singing Tree Rope Wrench is a friction device that allows the climber to ascend, descend and work the tree "Single Rope" with a friction hitch.
The ISC RP280 is the next step in the evolution of SRT work positioning. The sleeker design and rounded aluminum sideplates allow for less potential for damage to the climbers line and the set screw on the back pin allows for quick changeover betweendesired tethers.
It works by using leverage to force the rope into an S shape and providing friction for a controlled descent. When engaged, the Rope Wrench acts much like a conventional descent device such as a Figure eight.
When not engaged, the Rope Wrench provides no interference with ascending the rope. This allows the climber to work an entire tree using Single Rope Technique. Tethers for wrench sold separately.

The new Rope Wrench with Squirrel Tether is manufactured from aluminium, which ensures that twist and flex in the Rope Wrench system, is minimal. This means that the Rope Wrench remains in the optimal low friction position during ascent, (allowing the climber to achieve maximum climb efficiency), and ensures that the Wrench engages efficiently, as required during lateral movements and descent.

A medium duty rigging carabiner at a great price.
This triple action snaphook from ISC needs 3 separate actions to open and therefore is perfectly suitable for use in climbing activities where triple action connectors are required - in particular on fliplines and adjustable lanyards.
The triple action makes this snaphook legal to use in climbing competition.
The SH904 from ISC is the world's first triple action swivel eye snaphook. Design features include a Safety Heel to reduce snagging and a 'Blind' nose to reduce rope snagging. Ideal for use on safety lanyards and fliplines.

This means that the Rope Wrench remains in the optimal low friction position during ascent, (allowing the climber to achieve maximum climb efficiency), and ensures that the Wrench engages efficiently, as required during lateral movements and descent.
The Squirrel Tether can be used with an SRT Chest Harness, for hands-free tending of the system, while ascending. The Squirrel offers a choice of four SRT Chest Harness attachment points, allowing users to position their harness, according to the type of chest harness used- and to their personal preference.
The secondary aperture of the Squirrel Pulley provides an attachment point for the addition of a secondary system, which means that the Squirrel system can be used for rescues.
The Squirrel can be used with the 11-13mm Rope Wrench (RP280) and /or the new 13mm-optimized Rope Wrench (RP283).
