Frequently Asked Questions

How do I attach the rope grab to my rope?

Use a compatible locking carabiner (not included) through the attachment hole at the bottom of the device. Slide the rope through the side slot, ensuring the cam teeth face the load direction. Test by applying downward force—the cam should lock firmly.

Can I use this ascender for both ascending and fall arrest?

Yes. When used as an ascender, the rope grab allows smooth upward movement and locks under downward pressure. In fall arrest setups, it grips the rope instantly, preventing further descent ⚖️.

Will this work on kernmantle ropes?

This rope grab is optimized for 14–16 mm nylon kernmantle ropes. Using it on lines outside this diameter range may reduce gripping performance and safety.

How often should I inspect the device?

Inspect before each use. Check for signs of wear, deformation, or corrosion. Clean any debris from the cam mechanism and ensure smooth action. Retire immediately if any damage is detected .

Is lubrication required?

No regular lubrication is necessary. However, if the cam becomes stiff, apply a small amount of dry graphite powder to the pivot point—avoid oil-based lubricants that can attract dirt.

Usage Scenarios & Setup

Rock Climbing & Mountaineering: Use for safe rope-grab belays and ascending fixed lines on steep routes. Attach backup descender or belay device below for redundancy.

Arborist & Tree Work: Install on your climbing line to create frictionless ascents. Pair with a saddle and double-check your anchor for safe pruning operations.

Rescue & Evacuation: Rapid deployment in confined spaces for firefighter or tactical rescue teams. Combine with harness and backup rope system to secure victims.

Fall Protection: Integrate into industrial fall-arrest kit. The high-strength cam locks under sudden load, protecting workers at height.
