Teufelberger tREX 7/8 in Rigging Sling, 20 ft

The Teufelberger tREX rigging sling is a heavy 7/8 in sling made from Teufelberger's tREX rigging rope, here in a 20 ft length. It is built for wrapping large stems to hang a block or lowering device on big removals.

Where a heavy sling earns its keep

When you are blocking down big leaders or catching wood on a removal, the sling holding the block is the anchor for the whole system. A 7/8 in tREX sling gives you the diameter and strength to hang a large block on a big stem, with enough length to wrap a trunk several times or choke it.

Length matters: 20 ft wraps big wood, but on a smaller spar you will have extra to manage. Many crews keep a few lengths on the truck. See other heavy-duty slings to round out your set.

Most crews use a sling like this with a large rigging block, a lowering device at the base, and a rigging line sized to match. All of those parts need to be rated for the same job.

Rigging with it safely

Plan for dynamic loading. A piece that free-falls before the rope comes tight puts far more force on the sling than its weight suggests, so rate the whole system for the shock load and limit the drop.

Rig only within the rated strength of every component in the system, inspect gear before each job, and make sure the crew is trained in rigging practice under ANSI Z133 and the manufacturer's instructions. Retire a sling with cut strands, heavy abrasion, glazing, or a damaged eye.

Store slings clean and dry, out of the sun, and away from saw fuel and bar oil.
