A product called an ‘Impact Block’ it’s only purpose in life, apart from looking good, is to help absorb huge impacts created by the harsh dynamics of heavy arborist work. When rigged as part of an impact system, DMM blocks offer maximum security and strength with minimum fuss and weight. Every component, every curve, every surface has been analysed, designed and engineered to deliver the best performance in terms of dynamics, resistance and alignment.

The combination of high quality materials and our hot forging process gives a rope friendly, durable and robust block that can withstand the abuses of advanced tree felling and rigging work. These blocks have gone through a rigorous dynamic and static testing regime, and have been mis-treated and abused as much as possible; the end result is a highly functional product with an impressive strength to weight ratio. If ever there was a component in a safety chain destined to take abuse, this is it…

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.Designed for use in any industry when loads may be dropped onto 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 development, Impact Blocks have passed demanding dynamic, torsion and static testing regimes. The end result is a highly functional product with an incredible strength to weight ratio. These blocks were made to tolerate large forces and look good.
