Mechanicals – Mechanical Prusiks, Descenders & Rope Grabs

Mechanicals are advanced rope-handling devices used by professional arborists and climbers for controlled ascent, descent, and work positioning. This collection includes mechanical prusiks, rope grabs, and arborist descenders engineered for smooth performance on both SRT (Single Rope Technique) and MRS (Moving Rope System).

Unlike traditional friction hitches, mechanical climbing devices provide consistent friction, precise adjustment, reduced rope wear, and faster movement in the canopy. They are ideal for modern arborist climbing systems where efficiency, repeatability, and safety are critical.

Our Mechanicals category features industry-leading equipment from Petzl, Rock Exotica, ART, and Notch—trusted manufacturers known for professional-grade design, durability, and certified safety standards.

Designed For:

  • Arborist climbing and canopy work

  • Rope access and work positioning

  • Smooth ascent and controlled descent

  • SRT and MRS climbing systems

Mechanical prusiks and descenders are widely used by climbers who want predictable performance, cleaner rope management, and less variability than traditional knots/hitches. Whether you’re advancing on single rope or repositioning in the canopy, these devices deliver reliable control where it matters most.

Explore our selection of arborist mechanicals and build a climbing system optimized for speed, safety, and precision.
