Teufelberger tREX Whoopie Sling 16 mm – Adjustable Rigging Sling
The Yale 16mm Whoopie Sling-style Teufelberger tREX Whoopie Sling 16 mm gives you a tough, adjustable rigging sling built for arborist work and tree rigging. It uses Teufelberger’s tREX low-stretch hollow braid rope for strength, grip, and easy handling.
You can change the sling’s effective length in seconds. Slide the tail through the spliced bury to lengthen or shorten the sling. Once you set the length, the splice holds firm under load. This adjustability means you don’t need knots or hardware to set it up.
The rope has a 12-strand hollow braid construction. It resists twisting and feels supple in hand. Low stretch means you get predictable rope behaviour when you rig hardware or tie into anchors. The polyester cover stands up to abrasion on rough bark and in demanding rigging tasks.
This sling is typically made about 3 m long with a 16 mm diameter, giving you plenty of length for anchors and blocking points. The hi-vis colour helps you see it quickly in trees or on the ground.
You use this sling to anchor pulleys, set redirect points, or attach rigging hardware close to your anchor. Adjustable whoopie slings also let you tension lines easily without complex knots. Rigging setups become faster and cleaner.
Teufelberger’s tREX rope stays colour-fast thanks to solution-dyed fibres. A light wax coat keeps strands smooth and reduces snagging during use. This helps the sling stay easy to handle over repeated jobs.
Professionals who rig trees or set complex systems value this sling for its strength, adjustability, and smooth performance. You get a versatile tool that works on standard rigging, redirects, and custom anchor setups with minimal fuss.
