8928 D-Ring Extension, 18 Inch
The Miller 8928 solves the blind reach: an 18 inch webbing extension with a snap hook that clips to the dorsal D-ring and a D-ring on the other end that hangs where the worker can actually see and reach it. Connecting an SRL or lanyard stops being a two-person job.
Compatible with any brand of full body harness and built to meet OSHA and ANSI standards, the extension installs in seconds and stays on the harness as a permanent convenience upgrade.
Who Needs This Product
The extension is for anyone who has chased a dorsal D-ring with a snap hook they cannot see: solo workers, bulky winter gear, and SRL programs where workers connect and disconnect many times a shift. It also brings the connection point within reach for workers with limited shoulder mobility. Remember it adds 18 inches to the fall arrest system, which belongs in the fall clearance math.
Features
Reach Without the Contortion
The D-ring end hangs over the shoulder where the worker can see it, turning a blind fumble into a one-hand connection.
Locking Snap Hook
The snap hook end locks onto the harness dorsal D-ring and stays put as a semi-permanent installation.
Universal Compatibility
Works with any brand or style of full body harness with a standard dorsal D-ring.
High-Strength Webbing
Rated as a structural component of the personal fall arrest system, not a convenience strap.
Fast Setup
Clips on in seconds with no tools, and moves between harnesses just as fast.
Inspection Friendly
A simple two-hardware, one-strap build makes pre-use inspection a ten-second check.

Typical Applications
Installation Overview
- Open the locking snap hook and clip it to the harness dorsal D-ring.
- Confirm the gate is fully closed and locked on the D-ring.
- Route the extension over the shoulder so the D-ring end hangs within view.
- Connect the SRL or lanyard to the extension D-ring and verify the gate locks.
- Recheck fall clearance with the added 18 inches before working.
The extension stays installed on the harness between uses.
Inspection and Retirement
Inspect the extension with the harness before each use and during every competent person inspection.
- Webbing: cuts, frays, burns, chemical damage, or broken stitching.
- Snap hook: gate closes and locks, no cracks, corrosion, or distortion.
- D-ring: no cracks, corrosion, distortion, or sharp edges.
- Stitch patterns: intact at both hardware terminations.
Retirement triggers: any fall arrest event, any defect found during inspection, or any condition where the inspector cannot positively verify the extension is fit for service.
