Product information & specifications
DMM Impact Pulley Blocks
The DMM Impact Pulley Blocks are engineered for extreme rigging scenarios where loads may be dropped onto the system, generating significant dynamic forces. Designed for professional arborists, rigging specialists and rescue teams, these blocks combine exceptional strength, durability and rope-friendly performance in a lightweight, high-performance design.
Manufactured using advanced materials and precision engineering, Impact Blocks have been rigorously tested against dynamic, torsional and static loads, delivering a class-leading strength-to-weight ratio. Built to withstand the harshest environments, they provide reliable performance in even the most demanding rigging operations.
The latest Impact Block XS introduces a range of innovative upgrades, including an interlocking anchor bollard for double security, oversized bearings for improved efficiency, and a hollow axle design that enables advanced rigging configurations and easier maintenance.
Whether used for redirect rigging, winching or snatching timber, the DMM Impact Pulley Blocks deliver smooth rope handling, reduced friction and maximum control under load.
