FallTech 8366L - Dorsal D-Ring Extender w/ Choke-Loop, 18"

This D-ring extender provides 18 inches of additional reach from the harness dorsal attachment point, making it easier to connect lanyards or self-retracting lifelines. It is constructed with rugged 1-inch polyester webbing, includes a choke-loop for harness attachment at one end, and a plated alloy steel D-ring at the trailing end. Using the extender will increase the user’s total fall clearance distance when used with an energy-absorbing lanyard.

Key features:

• Extends the dorsal D-ring connection point by 18 inches for easier attachment of lanyards or SRLs
• 1-inch polyester webbing construction with high tensile strength
• Choke-loop harness attachment design for lighter weight and direct connection
• Plated alloy steel D-ring at the trailing end for secure anchorage connection

Q: How does this extender affect my fall-clearance calculation?
A: Using the extender adds its full 18-inch length to the dorsal connection reach and therefore increases the total fall-clearance distance when paired with a fall-arrest lanyard.

Q: Why use a choke-loop instead of a snap-hook for harness connection?
A: The choke-loop webbing attachment reduces added hardware weight at the attachment point and provides a clean connection for the user’s harness.

Q: Can this extender be used with both lanyards and self-retracting lifelines (SRLs)?
A: Yes — the extender enhances the dorsal D-ring reach so users can more easily attach either lanyards or SRLs.

Q: What should I inspect before each use of this extender?
A: Check the polyester webbing for cuts, abrasions, or exposed wear-indicating threads; verify the choke-loop is intact and properly secured; inspect the D-ring for deformation or corrosion; and ensure the webbing tab stitching is intact.
