⚡ At a Glance
- • Belay Control: Cam-assisted blocking with progressive rope feed for steadier catches and controlled lowers
- • Best for: Climbers who want reliable assisted braking and precise lowering at the gym and crag
- • Not ideal for: Rope systems outside the specified single-rope range or climbers needing integrated hands-free belay aids
Cam-assisted blocking tightens and pivots the cam to pinch and block the rope during a fall. Compatible with 8.5 to 11 mm dynamic single ropes, optimised for 8.9 to 10.5 mm.
Safer fall arrests – thanks to cam-assisted blocking
Cam-assisted blocking tightens the rope when the climber falls, causing the cam to pivot and pinch the rope, which creates a braking action. Compatibility with common single-rope diameters helps ensure the cam engages reliably.
Shorter, more secure catches reduce shock for both climber and belayer, making frequent attempts or bold lead falls less stressful.
Smooth lowering and feeding – with progressive rope feed and ergonomic handle
Progressive rope feed controls rope movement during belaying, while an ergonomic handle gives a comfortable grip and straightforward unblocking action. The mechanism balances friction and feed for predictable behaviour.
Controlled descents feel smoother and lowering a partner requires less abrupt braking, which improves confidence during practice and multi-pitch work.
Versatile for gym and crag – with wide rope compatibility
Designed for dynamic single ropes from 8.5 to 11 mm and optimised for 8.9 to 10.5 mm, covering most indoor and outdoor single-rope setups. Suitable for both top-rope and lead belaying.
One device covers typical indoor and outdoor ropes, so a single belay tool suits varied climbing sessions without frequent kit changes.
