FTC Donut Rigging Ring Pulley with Super Boa Sling

Hybrid Rigging Pulley Combining Sheave Power and Friction Control

The FTC Donut Rigging Ring Pulley is a unique hybrid device that merges the efficiency of a pulley with the braking stability of a friction ring. Designed for demanding arborist rigging, it supports both sheave‑based lifting and friction‑controlled lowering — or both simultaneously. Capable of handling dual‑rope setups, it excels in heavy‑load scenarios, delicate transfers and complex canopy operations.

Now Supplied with Super Boa Sling (3m, 4m or 5m)

Each Donut is supplied with a Super Boa Sling, known for its high strength, durability and flexibility in rigging applications. Available lengths:

• 3m Super Boa Sling
• 4m Super Boa Sling
• 5m Super Boa Sling

The Boa’s braided construction allows easy, secure anchoring to stems, spars and rigging points, offering excellent grip and adaptability.

Superior Friction Management for Controlled Lowering

Friction is essential in dynamic arborist rigging, and the Donut delivers stable, predictable friction that helps:

• Reduce load shock on rigging systems
• Improve control for ground operators
• Maintain smooth lowering even with heavy or unpredictable loads

This increased control results in safer rigging operations for climbers and grounds crews alike.

Intelligent Circular Shape for Foolproof Positioning

The Donut’s round, symmetrical design reduces incorrect loading, prevents overhang and allows efficient installation even between two axes. Multiple sling attachment points make it easier to fine‑tune its alignment for advanced rigging configurations.

Versatile for Ground or Aerial Rigging Setups

With its excellent strength‑to‑weight ratio, the Donut is suited to:

• Tree‑mounted rigging scenarios
• Ground‑based redirects
• Dual‑rope load sharing
• Multi‑anchor rigging layouts

It provides robust performance for both delicate sectional dismantles and high‑impact lowering operations.

Designed from Real‑World Arborist Input

Developed from hands‑on professional feedback, the Donut follows FTC TREE’s philosophy: durable, reliable, high‑performance tools that simplify rigging rather than complicate it. With sheave function, friction control, dual‑rope capability and precise sling placement, it expands rigging possibilities without unnecessary complexity.
