Kong Duck

Kong Duck micro ascender.

Probably the cutest piece of technical metalware, in the world...

The Duck is a sprung cam jammer which will work on ropes of diameter 8mm - 13mm. It will also (we think uniquely) grip on tubular or doubled tape slings.

At only 70g, and measuring under 6.5cm on its longest axis, it has a place in the gear of all vertical cavers or mountaineers. Very versatile, it can be considered for:

1. a spare jammer in case of loss or rescue;

2. a hand jammer in an ultra lighweight SRT kit, or;

3. as a very compact hauling assist (the design allows a hauling rope to run over the large fixed bollard through which the attachment krab is clipped, making a simple non-pulley jammer)
