DMM Impact Block - Large Pulley

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.

Features

• Rounded edges to cheek plates maintain low rope abrasion when the 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
