Round Sling

Wrap the round sling around the tree and shackle in your webbing or anchor webbing – your anchor point is done. Seamlessly sewn from endless webbing, far gentler on the bark than a single knotted strap.

Working load by colour

Both versions are made to EN 1492-2 with a sevenfold safety factor. The colour tells you the working load limit at a glance – that's an industry standard, not just styling:

• Black – WLL 1,000 kg. By the standard this would normally be violet; black is an approved special colour for the same load class. Enough for almost any park slackline setup.
• Green – WLL 2,000 kg. The next standard colour up, double the working load. Useful for longlines under high pre-tension, or whenever you'd simply rather have more margin.

Features

• Sewn round sling made from polyester webbing, as an endless loop
• Easier on the bark than a knotted strap, because the load spreads across the full width
• Fits all the common shackles and rings in our range
• Used as standard in our kits (for example the Sigma Impact Set), sold here on its own for restocking

Which length?

2 m fits around most park trees, 3 m for thicker trunks or if you'd rather have some margin. When in doubt, go a size up – too long can still be shortened by wrapping it an extra time, too short cannot be extended.
