Aeris Mono weblock





Aeris Mono is the most advanced and the lightest webbing anchoring device from Petram Slacklines. The body was machined out of single block of aluminium making it super lightweight yet strong and efficient.

With weight of just 100 grams, it’s the lightest full size weblock in the world. However it still have the size you would expect from a good weblock for convinient operations.

The main diverter with progressive geometry retains more than 90% of webbing strength. The height of the side plates allows the installation of thick or double lines. Combined with an internal width of almost 27 mm, it ensures smooth operation with most webbings available on the market.

Removable, automatic ball locking pin made of stainless steel is easy to use, increase the safety and comfort.

Additional string holds the webbing in place to prevent ‘tail walking’ effect and secure the pin so you won’t loose it when the weblock is open.

Aeris Mono allows direct mount of soft-release webbing but also has an additional hole in the back diverter for connecting soft shackles. It also allows to tension shorter lines by soft release strap or use hollow main diverter as built-in rigging plate.

Aeris Mono is designed for use with soft connectors only (soft release or soft shackle).
