Kong Italy Duck rope clamp for single ropes 8–13 mm, Blue/Black, 70 g compact emergency ascender

Kong Italy Duck is an ultra-compact, 70 g emergency rope clamp that locks single ropes 8–13 mm to stop downhill movement and assist in self-rescue and technical recovery.

Built and finished in Italy by Kong, the Duck rope clamp combines a toothless cam design, lightweight aluminum-alloy construction and an ergonomic handle so climbers, cavers and rescuers can deploy a dependable blocker quickly. Its compact footprint and large attachment hole make it suitable as a temporary ascender, a progress-capture device in hauling systems, or a safety regulator during technical manoeuvres.

How does the Duck rope clamp stop a person or load from sliding down?

The Duck uses a smooth, toothless cam that pinches and locks the rope under load without cutting fibers. When tension pulls downhill, the cam bites and arrests movement; release or controlled lowering is achieved by manipulating the ergonomic handle to release the cam.

• Toothless cam reduces rope wear compared with serrated cams
• Automatic locking under load prevents unintended descent
• Works reliably on single ropes 8–13 mm diameter
• Aluminum-alloy body balances strength and low weight (70 g)

Can I use the Duck for self-rescue and technical rescue scenarios?

Yes — Duck was conceived as an emergency ascender and recovery aid for self-rescue, rope progression and as a regulator in hauling or lowering systems. It is not a substitute for full rescue equipment but is a highly useful compact tool for temporary blocking and controlled transitions.

• Designed specifically for emergency blocking and temporary ascents
• Large attachment hole accepts a variety of locking carabiners and allows rotation
• Easy single-hand operation when time and dexterity are limited
• Lightweight and compact for carrying on harnesses or in rescue kits

What rope sizes and environments is Duck compatible with?

Duck performs best on single ropes between 8 mm and 13 mm diameter, covering most climbing, caving and arborist ropes. It is intended for technical outdoor use—mountaineering, caving, tree work and rescue—but should be used in accordance with standard rope techniques and manufacturer guidance.

• Compatible with single ropes 8–13 mm diameter
• Suitable for mountaineering, caving, tree climbing and rescue operations
• Aluminum alloy construction resists corrosion while staying light
• Not intended as a permanent load-bearing anchor replacement

How easy is Duck to manipulate under stress or with one hand?

The device features an ergonomic handle and intuitive geometry so users can engage and release the cam quickly, even when using one hand or wearing gloves. The layout reduces fumbling during urgent manoeuvres and supports confident, controlled operation.

• Ergonomic handle for secure grip and quick actuation
• Compact size allows rapid placement on the rope or strap
• Large attachment hole simplifies carabiner alignment and rotation
• Visual and tactile feedback aids correct placement under load

Who is this for: Climbers, cavers, arborists and professional rescuers looking for a lightweight, Italian-made emergency rope clamp will appreciate the Kong Italy Duck. It is ideal as a compact backup blocker in a rescue kit, a portability-minded ascender for technical progression, or an on-harness regulator when you need a fast, reliable way to arrest rope movement. Always follow rope-care and rescue protocols and inspect the device and rope before use.
