Pros & cons

Specifications

What this extension is for

Workers who can't comfortably reach their own dorsal D-ring — from harness fit, body size, or the D-ring's mounted position — and need the attachment point moved to where hands can clip in a lanyard, SRL, or rope grab connector. It sits in our D-ring extenders guide, forms the connector link described in the fall protection equipment guide, pairs with a lanyard from our fall protection lanyards guide, and matches harnesses from 3M's own ExoFit X100, ExoFit X200, and ExoFit X300 lines.

Compatibility

This extension attaches to a standard dorsal D-ring found across most DBI-SALA ExoFit harnesses, including the ExoFit Strata XP and ExoFit X300 — confirm your harness's D-ring style and rated capacity before ordering. The connecting end takes a rated carabiner such as the 3M DBI-SALA Saflok self-locking carabiner or the Petzl Bm’D carabiner.

How this extension compares

For the Protecta-branded equivalent with a stated 1.5 ft length, see the 3M Protecta 1385000. For a different end-connector style, compare the FallTech 836616 with a snap hook, the FallTech 8366 18 inch extender, the FallTech 8366L choking-loop version, or the KwikSafety Dolphin dorsal extender. 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. Recalculate your fall clearance with the extension's added length included, inspect it before every use, and retire it after any fall arrest.

Ordering FAQ

Is the 3M DBI-SALA 1231117 in stock and ready to ship?
Yes — 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 attaches to your harness’s dorsal D-ring and extends the attachment point out to where it’s easier to reach for self-connection or for a coworker helping with tie-off.

Does this listing specify a length?
3M’s listing for the 1231117 doesn’t publish a specific length figure — if you need a confirmed length, the sibling 3M Protecta 1385000 is stated at 1.5 ft; compare both against your reach needs.

Is this compatible with DBI-SALA ExoFit harnesses?
It’s designed to attach to a standard dorsal D-ring, which the ExoFit line uses — confirm your specific harness’s D-ring style and rated capacity before ordering.

What's the difference between this and the Protecta 1385000?
Both are 3M dorsal D-ring extensions; this is the DBI-SALA branded version, the 1385000 is Protecta PRO. Compare price, stated length, and which harness line you already own.

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.

Does this work with harnesses from other brands too?
If the other brand’s harness uses a standard dorsal D-ring compatible with this extension’s attachment point, yes — always confirm compatibility and rated capacity across both products first.

Why is this priced differently from the Protecta version?
3M prices its DBI-SALA and Protecta PRO lines independently even for similar accessory categories — compare current pricing on both linked listings rather than assuming parity.

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 or extension material 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.

Does adding this extension affect my fall clearance calculation?
Yes — any added length between the harness and the connecting device reduces available clearance. Recalculate your fall clearance with the extension included before relying on it.

Do I need one per harness?
One per harness that needs the added reach — if a worker rotates between multiple harnesses, 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.
