Simplex is the simpliest slackline device made for anchoring your webbing. This ring is designed for 20 and 25mm wide webbing. The rectangular shape allows you to chose inner width according to your webbing size giving you optimal geometry. The webbing retains more than 80% of it’s orginal strength. Locking mechanism allows you to pretension the webbing in one way, while it’s locked in the other way when used in single wrap option. Use Double wrap for maximum slippage prevention. Simplex works best with direct mounting to a shackle, preferably „Kingpin” style (Yes, we like this design) for best placement and maximum strengh. Minimalistic design lead to cheep, light weight and versitale device.

Simplex locker works best with aluminium shackles but stainless ones are also great option. 12mm bow or pin for ~25mm webbing and 10mm sheckle, bow or pin for ~20mm webbing.
