OMEGA-RQ 20mm Multi-Sling

RIGIQ OMEGA-RQ 20mm Rigging Multi-Sling - 500mm Spliced Eye Termination

The RIGIQ OMEGA-RQ Multi-Sling is a modern evolution of the traditional dead-eye sling, designed to give arborists greater versatility in everyday rigging setups. Built from RIGIQ OMEGA-RQ cordage, it delivers durable performance, dependable handling, and flexible use across a wide range of applications.

Designed with a large spliced eye, the Multi-Sling can be easily choked onto a product and used in multiple configurations. This makes it a highly adaptable rigging sling for tasks such as an anchor sling, mounting sling, or balancing sling.

A key benefit of the Multi-Sling design is that when tying knots, the splice sits behind the knot rather than in front, helping create a cleaner setup compared with a traditional dead-eye arrangement.

Key Features

• Made from RIGIQ OMEGA-RQ cordage
• Modern alternative to a traditional dead-eye sling
• Large spliced eye for versatile rigging configurations
• Can be used as an anchor sling, mounting sling, or balancing sling
• Easily choked onto products/components
• Splice position sits behind the knot in many knot-based setups
• Designed for reliable performance and long service life

Typical Applications

• Rigging anchor point creation
• Attaching rigging hardware/components
• Controlled lowering setups
• General arborist rigging use

Typical applications: arborist lowering operations, controlled dismantling, and general tree rigging setups.

Rope body: un-terminated:

• Minimum Breaking Strength (MBS) un-terminated
• Test standard: ISO 2307 using a bollard-type termination

Termination: Spliced Eyes:

• Spliced-Eye Strength Rating (Sigma-derived)
• Basis: Calculated using Sigma standard deviation from 5 tensile test results (hand-spliced eyes).
• Test setup: Pin-to-pin tensile test; pin Ø50 mm; eye internal length 500 mm; overall specimen length 2,500 mm; double braid construction.

Reporting note: The spliced-eye rating is configuration and method-dependent and is provided as a statistically derived performance rating. It should not be used as a substitute for rope-body MBS unless the end-use configuration matches the stated test setup.

Breaking Strength and Maximum Working Load

This product is supplied with breaking strength information (MBS/MBL). A maximum intended working load must be determined by the competent person by applying an appropriate Safety Factor (SF) to the breaking strength and ensuring the expected loads remain below that limit and below the ratings of all other components in the system.

Safety Factors (SF) / Design Factors

System Working Loads Rope and cordage systems are commonly managed using a Safety Factor (SF) (also referred to as a Design Factor or Coefficient of Utilisation). The Safety Factor is the relationship between the product’s breaking strength (e.g., MBS/MBL) and the maximum intended working load applied during use. The correct Safety Factor depends on the application, the environment, the expected loading type (static or dynamic), and the consequences of failure. In many rope rigging and lowering operations (including tree work), loads may be applied dynamically (e.g., during catches). The system and technique must be planned to minimise peak forces and avoid uncontrolled shock loading such as excessive free-fall, abrupt stops, or hard catches.

Typical Safety Factor guidance (set by the competent person/system designer):

• 5:1 – commonly used in controlled lifting system design
• 7:1 – commonly used for textile lifting slings in many EN-rated systems
• 10:1 (or higher) – often applied in rope rigging and lowering where dynamic effects and higher peak loads may occur

Important: These figures are provided as general guidance only. The required Safety Factor may be higher depending on the risk assessment, local regulations, industry practice, and operational conditions.

Note on terminology: “WLL” is typically a single limit assigned to equipment by the manufacturer under a defined standard. For rope systems, the competent person may determine a system working load / maximum intended working load by applying a Safety Factor appropriate to the task and conditions.

Always inspect rope and equipment before and after use. Retire any product showing signs of damage, excessive wear, contamination, heat damage, chemical exposure or other deterioration. Use only by trained and competent persons and in accordance with relevant industry best practice.
