STEIN 12mm Whoopie Sling Adjustable 1.0m to 3.5m

The STEIN 12mm Whoopie Sling is a strong, adjustable arborist rigging sling designed for fast, knotless rigging applications. Manufactured from STEIN OMEX-12, this lightweight and hard-wearing whoopie sling offers high strength, low stretch and excellent abrasion resistance for dependable day-to-day use in professional tree rigging systems.

Adjustable from 1.0m to 3.5m, this adjustable whoopie sling is ideal for arborists and tree surgeons who want quick setup, flexible rigging options and secure hardware positioning without the need to tie knots. The fixed eye helps hold hardware in place, while the adjustable eye allows fast and efficient length changes to suit different anchor points and rigging scenarios.

Designed for controlled lowering, anchor point setup and general rigging work, the STEIN 12mm Whoopie Sling is a practical, reliable addition to any professional arborist rigging kit.

Key Features

  • Adjustable whoopie sling for knotless arborist rigging applications
  • Adjustable length from 1.0m to 3.5m
  • Manufactured from STEIN OMEX-12 12-strand single braid rope
  • High strength with low stretch characteristics
  • Excellent abrasion resistance for demanding rigging environments
  • Fixed eye for secure hardware positioning
  • Adjustable eye for fast and flexible setup
  • Ideal for efficient anchor point and rigging system adjustment

How a Whoopie Sling Works

Whoopie slings are designed for knotless rigging applications. One end features a fixed eye for attaching hardware, while the other is fully adjustable. As part of the rope passes through the core of the sling, the outer sheath tightens firmly around the internal rope under load, creating a secure adjustable setup.

This specialised construction allows arborists to position and adjust hardware quickly without tying knots, making it a highly efficient choice for many day-to-day rigging tasks.

Why Choose STEIN OMEX-12?

The STEIN 12mm Whoopie Sling is manufactured from STEIN OMEX-12, a 12-strand single braid rope engineered for strength, low stretch and outstanding abrasion resistance. Its two-end per carrier construction creates a larger internal void, making it easier to splice, while the rope coating helps reduce snagging and improves long-term durability in demanding working environments.

This makes it a practical and dependable choice for arborists who need a rigging sling that can stand up to regular use in the tree and on the ground.

Ideal For

  • Professional arborists and tree surgeons
  • Knotless rigging setups
  • Fast anchor point adjustment
  • Controlled lowering and general rigging work
  • Attaching and positioning arborist rigging hardware

Important Use Note

Slack must be kept to an absolute minimum when using a whoopie sling. This product should only be used by trained and competent users who understand correct arborist rigging practices, inspection procedures and working load limitations.
