Ref: impactblock	DMM Impact Blocks Designed for use 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 the design process, 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. Watch them in action Features: Rounded edges to the 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. The lightweight attachment sling facilitates hauling of the block, sling and rope to the climber and helps with handling, in-tree stowage and workshop storage. Direct connection to cordage; the anchor sling 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. Technical specifications: CE certification to European Machinery Directive 2005 Hot forged cheek plates in 6082-T6 aluminium for high strength to weight ratio CNC machined from 6082-T6 Anodised to EN-12373-1:2001 Class I0EI Sealed for corrosion protection Stainless Steel 303 hollow spindle (IMB-L only) Stainless Steel 303 anchor pin (IMB-S), or 174 anchor pin (IMB-L) Efficient and robust Bronze self lubricating oilite bushings 6082-T6 aluminium alloy sheaves Download the PDF brochure
