Lightweight hightech weblock for 20mm slackline webbing
KingPin weblock for 20mm webbing
The original SLACKTIVITY aluminum shackle - the KingPin – has been upgraded! The new KingPin is a super light weblock for 20mm slackline webbings. This KingPin weblock has similar advantages of a weblock with minimal weight, such as higher breaking load efficiency (as a knot or ChainLock method) plus having the option to pre-tension the webbing.
The webbing can be easily pulled to the side with a manual pre-tensioning. With this release system, no softrelease is needed. We recommend using a softRelease when using a HangOver pulley with a 3: 1 ratio, since the webbing can wear out overtime during the release at higher sideways tensions.
The weblock unit, the KingPin body and the pin are connected with an elastic cord such that there are no loose parts which can be lost or separated. Overtime, the rubber cord can wear out, but it can be easily replaced with a standard 2mm rubber cord.
Another small feature is the option to insert / thread a cord or a 2mm safety pin through the two holes in the side panels. This can safely prevent a misalignment in rodeo lines that are attached high in the trees (and when regular control of the weblock is not possible)..
