A 1/2 in. soft sling for anchoring lowering devices and blocks without hardware.
This 1/2 in. soft anchor rigging sling gives you a quick, bark-friendly way to anchor rigging to a trunk or stem. It is sized and intended for mounting a port-a-wrap at the base of the tree.
A soft anchor sling wraps around the stem and holds its connection by the way it is formed, not by a steel shackle or ring. That keeps the weight down, spreads load over the bark, and makes it quick to set and remove.
At the base of the tree, it is a clean way to mount a port-a-wrap without chains or straps. More options are in our adjustable slings section.
Before each job, run the sling through your hands. Look for cut or pulled strands, glazed or melted fibers, flat or stiff spots, and heavy UV fading, and check that the splices and buries are intact. Retire it if you find damage you can't explain or after a shock load bigger than you planned for.
Match the sling diameter to the rest of the system and keep it within its rating. Rigging gear is for moving wood, not for life support. Match every component to the load with a working margin, follow the manufacturer's ratings and ANSI Z133, and make sure the crew is trained in rigging before relying on it. Note when each piece went into service, so worn gear gets retired on time instead of living on the truck for years.
