A 3/4 in rope sling with a large Beast ring for heavy friction rigging.
This 3/4 inch ring sling with Beast ring gives you a heavy-duty rigging point that is lighter than a big block. Choke the sling on the stem and run your rigging line over the large ring for friction, or clip a block to it.
A large rigging ring lets the rope bend over a wide radius, which is easier on the line than a small ring and adds friction at the top. That friction takes some load off the lowering device and helps control big pieces. A 3/4 inch sling suits the heavy end of the work, where the rigging point has to carry large wood.
Match the sling and ring rating to your rigging line and the loads you plan to catch. Compare other heavy-duty slings for different lengths and ends.
Rings also make rigging quicker to set. There is no sheave to line up and nothing to jam, so the climber can hang the sling, run the line and get back to cutting. When the job calls for repeated heavy lowering with less friction, clip a block to the ring instead. Choose a sling length that lets you choke the stem with the ring sitting where the rope will run cleanly.
Before each job, check the sling for cut or pulled strands, glazing, stiff spots and intact splices, and check the ring for grooves, gouges and sharp edges. Retire anything damaged or shock loaded beyond plan.
Rigging forces can be several times the weight of the piece. Use the maker's ratings, follow ANSI Z133 and keep rigging work to trained crews. Rigging gear is never used for life support.

For some work. A ring adds friction and saves weight, while a block runs freer for repeated heavy lowering.
For everyday pruning rigging, often. It is meant for heavy removal work and big wood.
