5/16" x 5 ft Type CDFXA2SL Adjustable 2-Leg Grade 100 Chain Sling - 9900 lbs WLL

Cartec CDFXA2SL Adjustable 2-Leg Chain Sling - CRFX Self-Locking Hooks with Integrated Adjusters

The Cartec CDFXA2SL Adjustable 2-Leg Chain Sling is a premium, streamlined lifting solution designed for maximum efficiency and enhanced load security. Built with Grade 100 alloy chain, this sling features a CDFXA2 master link assembly with integrated in-line adjusters, eliminating the need for bulky grab hook shorteners while allowing fast, precise leg length adjustment.

This configuration is equipped with Cartec CRFX self-locking hooks on each leg, providing automatic latch engagement under load for positive load retention. The result is a clean, compact sling profile that’s easier to handle, quicker to rig, and ideal for safety-critical lifting applications.

Available in sizes from 9/32" through 5/8", with Working Load Limits ranging from 7,400 lbs to 39,100 lbs (based on a 60° sling angle), the CDFXA2SL delivers a high-performance combination of strength, adjustability, and security.

Key Features

• Grade 100 alloy chain construction - high strength and fully certified
• CDFXA2 master link with integrated adjusters - no separate shortener legs or grab hooks required
• Cartec CRFX self-locking hooks - automatic latch engagement for enhanced safety
• Streamlined 2-leg configuration - reduced bulk vs. traditional adjustable slings
• Fast, precise leg length adjustment for balancing uneven loads
• Improved handling and reduced tangling on the jobsite
• Ideal for two-point lifting and stabilizing offset loads
• Individually serialized with metal load tag for traceability
• Load tag includes chain size, sling length, Working Load Limit, and serial number

Why Choose the CDFXA2SL Configuration?

Traditional adjustable slings rely on grab hooks mounted to short chain legs, which can add bulk and complexity. The CDFXA2SL integrates adjustment directly into the master link assembly, creating a more compact and refined sling design with fewer components and less clutter.

The addition of CRFX self-locking hooks makes this configuration ideal for overhead lifting and critical picks, where secure engagement and reduced risk of accidental release are essential. This setup delivers a similar experience to premium adjustable systems, combining speed, safety, and efficiency in one streamlined assembly.

Grade 100 alloy chain provides approximately 25% higher Working Load Limits than Grade 80 of the same diameter, allowing you to maximize lifting capacity without increasing sling weight.

Understanding Sling Angle and Capacity

Working Load Limits are based on a 60° sling angle. As sling angles decrease (legs become more horizontal), tension on each leg increases significantly, reducing overall capacity. Always follow proper rigging charts and account for sling angle in every lift.

Typical Applications

• Structural steel erection
• Heavy equipment and machinery lifting
• Precast and concrete handling
• Industrial maintenance and shutdown work
• Critical lifts requiring enhanced hook security

Frequently Asked Questions

What does “SL” mean?
SL stands for self-locking, indicating the sling is equipped with hooks that automatically close and lock under load.

What is the CRFX hook?
The Cartec CRFX is a self-locking sling hook designed for secure, automatic engagement during lifting operations, reducing the risk of accidental disengagement.

How is this different from a traditional adjustable sling?
This sling uses integrated in-line adjusters instead of separate grab hook shorteners, resulting in a cleaner, more compact design that’s easier to use and faster to rig.

Are these slings certified?
Yes. Each sling is individually serialized and tagged with chain size, sling length, Working Load Limit, and a unique identifier for traceability.

Important Safety Information

• Use only by trained and qualified personnel.
• Never exceed the Working Load Limit.
• Account for sling angle reductions - capacity decreases below 60°.
• Inspect chain, master link assembly, adjusters, and hooks before each use.
• Ensure CRFX hooks are fully engaged and functioning properly prior to lifting.
• Remove from service if any component shows signs of wear, deformation, or damage.
