FallTech 8366L 18 D Ring Extension with Choking Loop

An 18 d ring extension that wraps a structure — FallTech 8366L

Most D-ring extenders assume you already have an anchor to clip into; this 18 d ring extension works when you don't. The FallTech 8366L pairs a choking loop — a webbing loop that cinches around a beam, post, or other structural member — with a D-ring at the opposite end, so it can create a wrap-around anchor point and then hand off a rated attachment for your lanyard or SRL.

Shoppers searching a d ring extension strap to wrap around structure rather than clip to an existing D-ring, or a harness lanyard extension and a d ring extension lanyard for extra reach, land on the 8366L.

• 18 inch webbing extension
• Choking loop end cinches around a beam, post, or structural member

Pros & cons

Specifications

What this extension is for

Anchoring around a beam, post, or other structural member where no D-ring or bolt-on anchor already exists, or extending a harness's dorsal D-ring depending on how it's rigged. It sits in our D-ring extenders guide, supports the anchorage guidance in the anchor requirements reference, forms the connector link described in the fall protection equipment guide, and pairs with a lanyard from our fall protection lanyards guide.

Compatibility

The D-ring end takes any rated connector sized to its opening — a carabiner such as the Petzl Bm’D or the 3M DBI-SALA Saflok, or a lanyard's own snap hook. Anchor point selection and rating should follow the anchor points collection guidance for whatever structure the choking loop wraps — for a cross-arm strap alternative on steel beams, see the Guardian 10787 cross arm strap or the Guardian X-Arm 48.

How this extension compares

For a version that clips to an existing D-ring instead of wrapping structure, see the FallTech 836616 with a snap hook or the plain FallTech 8366. For a 3M dorsal D-ring extension instead of a wrap-around anchor strap, compare the 3M Protecta 1385000, the 3M DBI-SALA 1231117, or the KwikSafety Dolphin extender. Every connector and extension in stock is in the carabiners & connectors collection, anchor hardware is covered in our best roof anchors guide, and the full field lives in the fall protection collection.

Safety note: a choking loop extension is one component of a personal fall arrest system — the structure it wraps must be assessed by a qualified person for adequate strength, and the full rig still needs a rated harness and a compliant lanyard or lifeline under OSHA 1926.502. Recalculate fall clearance with the extension's length included, inspect the webbing and D-ring before every use, and retire it after any fall arrest.

Ordering FAQ

Is the FallTech 8366L 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 is a choking loop?
A webbing loop that cinches down around a beam, post, or other structural member when tensioned, creating a wrap-around anchor point without needing a fixed anchor already installed.

How long is this extension?
18 inches — the fixed length of this listing, giving a set amount of reach or wrap-around room.

What's at the other end from the choking loop?
A D-ring — it gives you a rated attachment point to clip a lanyard, SRL, or rope grab connector to once the choking loop end is wrapped and cinched around the structure.

How is this different from the FallTech 836616 with a snap hook?
Both are FallTech D-ring extenders; the 836616 is a 16 inch extender ending in a snap hook for clipping to an existing D-ring, while this 8366L is 18 inches and ends in a choking loop for wrapping around a beam or post instead.

Can I use this as an anchor strap around a beam?
The choking loop end is designed to wrap and cinch around suitable structural members — confirm the structure’s rating and your anchor point selection meets OSHA requirements before tying off to it.

What connects to the D-ring end?
A lanyard, SRL, or rope grab connector with hardware rated for this D-ring’s opening and capacity — check your connecting device’s listing for compatibility.

Is this compatible with any harness or anchor setup?
The choking loop wraps a structure to create an anchor, or the D-ring end can extend a harness’s dorsal D-ring depending on how you rig it — confirm your specific use case against FallTech’s instructions.

Is this OSHA compliant?
As a connector or anchor strap component it forms part of a compliant rig when the structure, harness, and lanyard or lifeline together meet 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, confirm the choking loop cinches and holds under tension, and check the D-ring for deformation or wear. Retire after any fall arrest.

Does using this as an anchor strap affect fall clearance?
Yes — any added length between the anchor and the worker reduces available clearance. Recalculate your fall clearance with this extension’s length included before relying on it.

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