FORESTER Arborist Whoopie Sling 1/2" x 3–5' Adjustable Rigging Sling — 11,000 lb Break, 1,750 lb WLL

FORESTER Arborist Whoopie Sling is an adjustable 1/2" rigging sling that converts from 3' to 5' and delivers a compact, reliable anchor for porta wrap, lowering, and general tree rigging.

This whoopie sling is built for arborists who need a lightweight, versatile connection that adjusts quickly in the field. Constructed with high-strength components, it combines a small packing footprint with a high breaking strength so you can set anchors, tension rigging systems, and run lowering lines without bulky hardware. The adjustable eyes let the sling conform to different trunk diameters and rigging points while keeping the working setup tidy and simple to modify.

How does this sling adapt to different rigging heights and tree sizes?

The internal whoopie splice lets you shorten or lengthen the sling smoothly, giving a usable span from three to five feet. That range covers common anchor positions from near-ground wraps to higher crown connections and integrates well with X-rigging and other systems. The stationary eye preserves a fixed loop when you need a dedicated attachment point.

• Adjustable whoopie splice for quick length changes.
• 3' to 5' working range to fit multiple tree diameters.
• Stationary eye for stable, repeatable anchors.

What strength and safety properties does the sling offer?

The sling is engineered for heavy-duty rigging with an 11,000 lb maximum breaking strength and a recommended working load limit of 1,750 lb. Those ratings make it suitable for typical arborist lowering and anchor tasks when used within industry-standard safety systems. Always follow your company protocols and inspect webbing and splices before each use.

• 11,000 lb breaking strength for robust performance.
• 1,750 lb working load limit for routine rigging loads.
• Made from high-strength materials for durability and abrasion resistance.

How does this sling integrate with porta wrap, lowering devices, and common gear?

The sling is tailored to serve as an anchor for a porta wrap and to interface with lowering devices, pulleys, and carabiners. Its adjustable eye and compact profile reduce excess webbing and make rigging tidy and easier to manage. Use it as either an adjustable anchor or a fixed connection depending on the task at hand.

• Works as an anchor for porta wrap and lowering systems.
• Compatible with carabiners, pulleys, and most arborist hardware.
• Compact design minimizes snagging and excess webbing in the canopy.

How quick and simple is setup and adjustment on the job?

The whoopie splice is designed for rapid adjustment so you can change length without complex knots or tools. Setting the sling takes seconds: form the stationary eye, adjust the splice to the target length, and clip your hardware. This simplified setup cuts time aloft and reduces the chance for user error during transitions.

• Fast whoopie-splice adjustments—no special tools needed.
• Stationary eye pre-formed for immediate attachment.
• Minimal packing weight for easy transport between jobs.
