The ISC Arborist Redirect double pulley was developed by tree climbers. The ISC RP031 is a very compact double pulley for easy installation. Designed specifically for the redirecting of a doubled rope in a DbRT system. The Arborist Redirect features swinging side plates without a center plate, making it very easy to install ropes - not many, if any pulleys have this feature. It's spec'ed for ropes 12mm in diameter but our trials show it will work up on ropes to 13mm in diameter with comfort. The spindle has a a minimum breaking strength of 35kN and the sheaves are rated to 15kN each way. Approved to BS EN 12278. Made in Wales by ISC and each unit is 100% inspected and is laser numbered for easy PPE log management.
