DMM combines high-quality materials with advanced manufacturing processes to create a block that is both rope-friendly and extremely robust. At the same time, its optimised design keeps weight low without compromising strength. This balance gives the block an outstanding strength-to-weight ratio.
These impact blocks have passed rigorous dynamic, torsion, and static testing. Therefore, you can rely on them to perform under extreme conditions. The rounded cheek plates reduce rope abrasion, while fairlead flares maintain efficient rope alignment during use.
Additionally, thrust surfaces improve resistance to side loading on the spindle and anchor pin. The integrated lightweight attachment sling makes hauling and positioning easier. It also helps with storage and organisation in the tree or workshop.
The block connects directly to cordage, which ensures compatibility with other components in your rigging system. Furthermore, high-efficiency oilite bushings reduce friction and improve overall performance. Each unit is individually marked for traceability, and the colour coding follows EU WLL protocols for quick identification.
