Product description

Designed for use in the tree care industry when loads may be dropped into rigging with considerable impact forces. The combination of high quality materials and advanced production processes has ensured a rope friendly, durable and robust product. During design each Impact Block has gone through a thorough dynamic and static testing regime, the end result is a highly functional product with an impressive strength to weight ratio.


Rounded edges to cheekplates maintain low rope abrasion when rope is fed ‘unfair’
Fairlead flares help maintain high working efficiency
Thrust surfaces increase tolerance to external loading of spindle and anchor pin
Lightweight attachment sling facilitates hauling of block, sling and rope to the climber and helps with handling, in tree stowage and workshop storage
Direct connection to cordage, the anchor slings helps ensure correct neighbour component compatibility
High efficiency oilite bushings to reduce friction
Colouring follows EU WLL protocol
Individual serial marking
Made in Wales, UK

Suggested Areas of Application

Tree care – dismantling operations
Forestry – winching operations
