Pros & cons

Specifications

What this extension is for

Workers who can't comfortably reach their own dorsal D-ring — whether from harness fit, body size, or the D-ring's position — and need the attachment point brought forward or down to where hands can clip in a lanyard, SRL, or rope grab connector. It sits in our D-ring extenders guide, supports the fit guidance in the how to put on a safety harness reference, forms the connector link described in the fall protection equipment guide, pairs with a lanyard from our fall protection lanyards guide, and pairs with any harness from the full body harness collection, including 3M's own Protecta PRO harness and the Protecta comfort construction harness.

Compatibility

This extension attaches to a standard dorsal D-ring — confirm your harness's D-ring style and rated capacity before ordering. Its counterpart on 3M's DBI-SALA line is the 3M DBI-SALA 1231117; check which D-ring style your specific harness uses. The connecting end takes a rated carabiner such as the 3M DBI-SALA Saflok self-locking carabiner.

How this extension compares

For a different end-connector style, see the FallTech 836616 with a snap hook, the plain FallTech 8366 18 inch extender, or the FallTech 8366L choking-loop version. 3M's own web extender option is the 3M DBI-SALA 18 inch web extender, and the connecting hardware pairs well with the Petzl Bm’D carabiner. Every connector and extension in stock is in the carabiners & connectors collection, and harness selection is covered in our best safety harness guide.

Safety note: a D-ring extension is one component of a personal fall arrest system — it must be paired with a properly fitted full body harness, a rated lanyard or lifeline, and a rated anchor meeting OSHA 1926.502. Confirm the extension does not compromise clearance distance for your fall arrest calculation, inspect the webbing and connector before every use, and retire it after any fall arrest.

Ordering FAQ

Is the 3M Protecta 1385000 in stock and ready to ship?
This listing is active and ships through Amazon. Open the linked listing for live price, availability, and delivery speed.

What does this D-ring extension do?
It moves your harness’s dorsal attachment point 1.5 ft further from your back, bringing it within easier reach for self-connection or for a coworker assisting with tie-off.

How long is the extension?
1.5 ft. That’s the fixed length of this listing — if you need a different reach, compare other lengths in the D-ring extenders guide before ordering.

Does this fit any harness?
It’s designed to attach to a standard dorsal D-ring; confirm your harness’s D-ring style and rated capacity are compatible with this extension before use.

Why would I extend the dorsal D-ring?
Some workers can’t comfortably reach their own dorsal D-ring to self-connect a lanyard or SRL — an extension brings the attachment point forward or down to a reachable spot.

What's the difference between this and a FallTech D-ring extender?
Both extend the dorsal attachment point; they differ by brand, length options, and end-connector style (snap hook versus choking loop). Compare the FallTech 8366 line if you want a snap-hook or choking-loop end instead.

Does this replace my harness's D-ring?
No — it attaches to your existing dorsal D-ring and extends from it; the harness’s built-in D-ring and its rating are unchanged.

Is this compatible with 3M DBI-SALA harnesses too?
This 1385000 is the Protecta PRO version; 3M’s DBI-SALA line has its own extension listing (the 1231117) — check which D-ring style your specific harness uses before ordering.

What connects to the loose end?
A lanyard, SRL, or rope grab connector rated for the extension’s attachment point — match your connecting device’s hardware to the extension’s loop or hook.

Is this OSHA compliant?
As a connector component it forms part of a compliant rig when paired with a rated harness, lanyard or lifeline, and anchor under OSHA 1926.502 — the extension itself is one link in that chain.

How do I inspect it before use?
Check the webbing for cuts, fraying, UV damage, or chemical staining, and confirm the stitching and end connector show no deformation or wear. Retire after any fall arrest.

Do I need one per harness or one per worker?
One per harness that needs the reach — if a worker uses more than one harness, each would need its own extension or a shared one moved between them.

How do I reorder for a crew?
Reorder from this page — the listing and its linked Amazon ASIN stay constant, so equipping every harness that needs the extra reach takes seconds.
