Rigging

This 3/4 in. whoopie ring sling combines an adjustable whoopie body with an XL ring, giving a smooth, low-friction rigging point that fits stems of different sizes.

How the ring sling works

A whoopie sling adjusts by sliding the tail through a hollow-braid section; under load the braid grips and holds the length. Put a large ring on it and you have a light rigging point the rope can run through, or a place to clip a block.

The XL ring gives the rope a broad radius to run over, which is easier on line than a small ring. See more adjustable slings for other sizes.

Use and inspection

Set the sling snug around a sound stem and keep the ring loaded in line, not side-loaded across a crotch. A ring builds more friction than a block, which helps on small wood but adds wear, so watch the rope and ring surface.

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. 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.
