Flip Lines for Professional Work Positioning
Flip lines (also called fliplines or wire-core positioning lanyards) help arborists, utility workers, and tower technicians maintain a secure, hands-free working position in trees, on poles, and on structures. They are designed to hold position, not arrest a fall, and should always be used with a separate primary fall protection system.

Professional Fliplines for Arborist Work Positioning
Why U.S. Rigging Flip Lines
For over 40 years, U.S. Rigging has manufactured and distributed climbing ropes, fall protection, and industrial rigging used by arborists, utilities, and tower crews across North America. Our flip lines are built with high‑visibility jackets, quality wire cores, and hardware that meets or exceeds ANSI work‑positioning standards.

What is a Flip line?
A flip line is a work‑positioning lanyard with a steel wire core that holds its shape so it can be “flipped” around a tree trunk or utility pole and advanced as you climb. The rigid core prevents sagging, making it easier to move the flip line up the stem while an adjuster or prusik fine‑tunes your working position.
Key Characteristics of Fliplines
-
Steel Wire Core: Maintains shape for easy flipping around trees and poles
-
Protective Sheath: Durable cover protects wire core from damage and weather
-
Adjustable Length: Rope grab or prusik allows length adjustment
-
Quick Repositioning: Can be advanced rapidly during climbing
-
Hands-Free Support: Provides stable work positioning
-
Swivel Snaps: Prevent twisting during use
-
Professional Grade: Built for daily arborist and utility work
-
ANSI Compliant: Meets work positioning standards
Important Safety Note: Fliplines are work positioning devices, not fall arrest equipment. Always use a separate fall arrest system (climbing line with friction hitch, SRL, or fall arrest lanyard) as primary fall protection when using fliplines.
Flipline Components
Steel Wire Core
-
Flexible steel wire (e.g., 7x19 construction) for strength and shape retention.
-
Galvanized or stainless options for corrosion resistance in harsh environments.
Protective Sheath
-
Polyester or nylon cover for abrasion resistance, UV stability, and comfortable handling.
-
High‑visibility colors for better line awareness in trees and on poles.
Adjustment System
-
Rope grab adjusters for straightforward, durable adjustment.
-
Prusik or cam‑style adjusters for smooth, incremental positioning.
End Terminations
-
Swivel snap hooks and locking carabiners for secure attachment.
-
Sewn or thimble‑reinforced eyes for maximum strength and durability.
Types of Fliplines
Standard Wire Core Flip lines
-
Steel‑core flip lines with durable polyester sheath in common working lengths (8–16 ft).
-
Ideal for everyday arborist tree work and utility pole positioning.
Adjustable Flip lines Systems
-
Flip lines with integrated rope grabs or advanced adjusters for quick, one‑handed length changes.
-
Best for climbers who frequently move between different trunk or pole diameters.
Specialty Flip Lines and Kits
-
Complete flip‑line kits with prusiks, carabiners, and hardware ready to clip in.
-
Heavy‑duty models for utility and tower work where abrasion and contamination are common.
Common Applications
Common uses for flip lines
-
Arborist tree climbing, pruning, removals, and canopy positioning
-
Utility pole climbing for electrical and telecom work
-
Tower and structure access for inspection and equipment installation
-
Training, rescue practice, and storm‑response tree work
Choosing a Flip Line
How to Choose the Right Flip Line
-
Length: 8–10 ft for small trees and poles, 12 ft as a common all‑around choice, 14–16 ft for larger stems.
-
Diameter and weight: Choose a diameter that feels comfortable in hand while balancing weight and durability.
-
Adjuster: Rope grab for simplicity and robustness; advanced adjusters for frequent repositioning.
-
Environment: Galvanized vs stainless and sheath durability based on your climate and work conditions.
-
Compliance: Confirm ANSI Z133 and other applicable standards for your work.
Proper Use, Inspection & Maintenance
Safe Use Best Practices
-
Always climb with an independent fall‑arrest system in addition to your flip line.
-
Attach to side D‑rings, maintain a snug working stance against the tree or pole, and advance the flip line in smooth, controlled motions.
-
Inspect hardware, sheath, and wire core before every climb and retire any line with kinks, broken wires, core exposure, or damaged hardware.
Care and Maintenance
-
Clean with mild soap and water, dry completely, and store in a cool, dry place away from fuel and chemicals.
-
Lubricate wire cores as recommended by the manufacturer and keep basic usage and inspection records for professional programs.
Frequently Asked Questions
What's the difference between a flipline and a positioning lanyard?
Flipline is a specific type of positioning lanyard with a steel wire core that maintains its shape. The wire core allows it to be "flipped" around trees or poles for quick repositioning. Other positioning lanyards may use rope or webbing without a wire core. Fliplines are preferred by arborists and utility workers for their ease of repositioning during climbing.
Can I use a flipline as my only fall protection?
No. Fliplines are work positioning devices, not fall arrest equipment. ANSI Z133 and OSHA require a separate fall arrest system (climbing line with friction hitch, SRL, or fall arrest lanyard) as primary fall protection. The flipline provides work support; the fall arrest system provides life safety protection.
How do I know when my flipline wire core is damaged?
Run your hands along the entire length feeling for kinks, bulges, or broken wires. Visually inspect for any exposed wire through the sheath. Any kinks, broken wires, or core exposure requires immediate retirement. The wire core should be smooth and uniform throughout its length. Regular inspection is critical for safety.
What length flipline should I use?
Choose based on the typical diameter of trees or poles you work on. A 12-foot flipline is most common and versatile for average trees. Larger trees may require 14-16 feet. Utility pole work often uses shorter lengths (8-10 feet). The flipline must wrap around with enough length to adjust for comfortable positioning.
How often should I lubricate my flipline?
Follow manufacturer recommendations, typically every few months with regular use or when the wire core feels dry or stiff. Use appropriate wire rope lubricant. Proper lubrication prevents corrosion, reduces friction, and extends service life. Avoid over-lubricating, which can attract dirt and debris.
