The CMI RopeJack is a mechanical advantage tool for quickly and easily pre-tensioning static lines, light lifting, and cabling. The RopeJack is small and light enough to be carried aloft by a climber, and the length of the handle on the RopeJack limits excessive loading in order to avoid rope damage. The CMI RopeJack is used to remove slack and stretch for lowering and to lift the tips on light limbs without having to break out the big guns. Simply attach both ascenders to your line and crank away to tighten a static line or climb a rope.

With years of development and testing already under their belt, the RPM has become an incredibly versatile modular system that works smoothly and efficiently. The revolutionary Pulley/Prusik-minding modular structure is a high strength, torsion-resistant building block suitable for rescue, rigging and hauling applications. The swivelling, shackle body accepts various cartridges to allow a multitude of configurations and a certified friction prusik cord interfacing with prusik-minding cheek plates does all of the holding work with minimal 'sit back'. The prusik can be installed at either end to give the option of top or bottom control.
