DMM Impact Block – DMMIMB

DMM’s strongest ever product! Designed for use in any industry where 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, robust block that looks amazing and performs even better. Lightweight in mass but not strength, our Impact Blocks have passed incredible dynamic, torsion and static tests – a true testament to their strength to weight ratio.
