Aluminum Alloy Ergonomic Hand Ascender

A lightweight handled ascender specifically designed for Single Rope Technique (SRT), arboriculture, rescue, and work at heights. The handle features an ergonomic dual-material injection-molded design, complete with a dedicated index finger groove and an anti-slip base to minimize fatigue during prolonged ascents. Internally equipped with a multi-arc stainless steel toothed cam and a self-cleaning mud channel, it ensures a secure grip even on wet, icy, or muddy ropes. It supports rapid, one-handed attachment and removal at any point on the rope.

Key Features

• Ergonomic Injection-Molded Grip: The non-slip rubberized handle features a dedicated index finger groove, while the widened base prevents the hand from slipping, ensuring a firm and stable grip even when wearing thick gloves.

• Multi-Arc Self-Cleaning Toothed Cam: The optimized tooth geometry ensures minimal resistance during upward travel, while providing instantaneous engagement under load. The integrated mud channels effectively clear away debris, ice, and water without damaging the rope sheath.

• One-Handed Quick Release: The safety cam lever is designed for intuitive one-handed operation, allowing for rapid attachment or detachment at any position on the rope without the need to remove carabiners.

• Dual Connection Point Design:

  • Top Attachment Hole: Can be used with a carabiner for rope-retention purposes or to mount a pulley for mechanical advantage and directional rigging.

  • Bottom Attachment Hole: Ample space allows for the simultaneous connection of a lanyard and foot loop carabiners without interference.

• High-Standard Load Capacity: Features a working load of up to 500kg and a single-person safety rated load of 150kg, compliant with the XF494-2023 standard.
