⚡ At a Glance
  • Hold Variety: Modular screw-in grips can be unscrewed and repositioned to create many distinct hold shapes and orientations
  • Best for: Bouldering enthusiasts, climbers wanting finger-strength maintenance, and users needing targeted hand mobility work
  • Not ideal for: People seeking whole-body climbing practice or large-scale training boards

Modular screw-in grips enable infinitely customisable routes and difficulty. Portable, rock-like 3D holds let climbers train grip and dexterity away from the gym.


Endless Route Variety – thanks to modular screw-in grips

A simple screw-and-segment system lets each grip be unscrewed and repositioned to form different sequences and orientations. The modular approach supports many combinations without specialised tools.

Create progressive sessions by altering hold shape and spacing, so finger training can match evolving skill levels. Route-setting practice sharpens problem-solving alongside strength work.

Build Finger Strength Anywhere – with realistic 3D rock-like holds

Three-dimensional holds mimic the contours and textures of outdoor rock, emphasising finger pads, edges and slopers during pulls and crimps. The geometry targets specific tendon and pulley engagement used in climbing.

Short, frequent sessions improve grip endurance and dexterity that transfer to outdoor and gym moves. Lightweight portability means training can continue on trips, in offices or between climbs.

Improve Focus and Calmness – with tactile, puzzle-like design

Interlocking routes and variable grips turn training into a tactile puzzle that requires concentration and sequencing. Repeated interactions provide sensory feedback that encourages steady, controlled movements.

Use as a focused warm-up or a calming fidget that also trains hands; sessions help reduce anxiety while keeping fingers active. Suitable for rehabilitation exercises aimed at improving hand mobility.
