KingPin | The Aluminium Shackle

KingPin | The Aluminium Shackle

Let us present the new master-piece of SLACKTIVITY – the «KingPin». The elegant and functional design has been tested, analyzed and further developed in countless 3D-print-models. This aluminium shackle weighs only 107g (incl. PushPin and rubber cord), has a minimal breaking strength of 60kN (6 tons), and is made of aircraft aluminium (AL7075).

The shape, features and function of the aluminium shackle have been developed especially for the needs of slackliners. The mouth opening of 26mm width allows optimal handling to clip end loops, the deadManplate, softRelease and 25mm-webbings. The high side plates offer perfect guidance for softRelease or primitive pulleys.

The spacey bow of the shackle offers enough space for round slings or the SLACKTIVITY tree loops. The areas standing 120° to one another allow that chainlocks lie at a perfect angle on the shackle surface. The PushPin made of stainless steel with 11.2mm diameter has been weight-optimized and is super easy to use. The rubber cord connects to the free turning PushPin with the shackle body. With some exercise, the KingPin can even be handled one-handed, which can be very useful, especially in highline use.
