DMM Impact Blocks

The DMM Impact Blocks are lightweight in mass but not strength, the DMM Impact Blocks have passed incredible dynamic, torsion and static tests - a true testament to their strength to weight ratio.

The Small Impact Block: The Small Impact Block is small by name, small by nature (relatively speaking) yet still big in strength. With a massive Minimum Breaking Strength (MBS) of 200kN and a Working Load Limit (WLL) of 40kN, it is incredibly strong, yet can almost be carried around on a harness.

The Large Impact Block: With a massive Minimum Breaking Strength (MBS) of 300kN and a Working Load Limit (WLL) of 60kN, the Large Impact Block sets new standards in handling massive drops.

Features:
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
