Petzl Bm'D Fall Protection Carabiner — Aluminum Locking Connector

An aluminum locking fall protection carabiner — Petzl Bm'D

Every fall arrest system needs a connector between the worker and the device — a lanyard, a rope grab, an SRL — and a fall protection carabiner is one of the standard ways to make that link. The Petzl Bm'D is an aluminum locking carabiner built for exactly that: clip it to a harness D-ring, connect your device to the gate side, and the lock keeps it from swinging open under a snag load.

Shoppers searching a petzl carabiner for their fall protection kit, or a carabiner connector to bridge a harness and a lanyard or rope grab, land on the Bm'D. It's the true locking-carabiner counterpart to Petzl's gated EASHOOK connector.

Pros & cons

Specifications

What the Bm'D is for

Any fall arrest connection point where a locking carabiner is specified over a fixed snap hook — the harness end of a lanyard, the D-ring side of a rope grab, or an anchor strap connection. It sits in the carabiners & connectors collection, supports the harness compatibility covered in our D-ring extenders guide, forms the connector link described in the fall protection equipment guide, and pairs with a harness from our ranked harness guide and lanyards ranked in the fall protection lanyards guide — including Petzl's own Absorbica Y 150 lanyard, Absorbica Y 80 lanyard, ASAP’Sorber Axess energy absorber lanyard, and J08452 ASAP’Sorber ANSI lanyard.

Compatibility

Confirm the gate opening on the Bm'D matches the rated connection point on your lanyard, rope grab, or SRL before ordering — most standard fall-arrest D-rings and connector loops are compatible, but always check both listings. For a fixed-hook alternative rather than a locking carabiner, see the Petzl EASHOOK open connector or the FallTech 836616 D-ring extender with snap hook. If you need reach rather than a different gate style, a D-ring extender or the KwikSafety Dolphin extender solves that instead.

How the Bm'D compares

The closest direct alternative is the 3M DBI-SALA Saflok self-locking carabiner — same locking-carabiner role, different brand and gate mechanism. For a lanyard that already includes a carabiner-style twin-leg connector, see the Elk River 35417 twin-leg carabiner lanyard. Every connector option in stock is in the carabiners & connectors collection, and the full fall protection field lives in the fall protection collection.

Safety note: a carabiner like the Bm'D is one part of a personal fall arrest system — it must be paired with a rated lanyard or lifeline, a full body harness, and a rated anchor meeting OSHA 1926.502 to function as intended. Confirm gate-to-connector compatibility, inspect the locking mechanism before every use, and retire the carabiner after any fall arrest or if the gate no longer locks reliably.

Ordering FAQ

Is the Petzl Bm'D 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 the Bm'D carabiner used for?
Connecting devices — a lanyard, rope grab, or self-retracting lifeline — to a harness D-ring or a rated anchor point, wherever a system calls for a locking carabiner rather than a fixed snap hook.

Is this a locking carabiner?
Yes — Petzl markets the Bm'D as an aluminum locking carabiner, meaning the gate requires a deliberate action to open rather than swinging open under a snag load.

What is the Bm'D made of?
Aluminum — lighter than a steel carabiner of similar strength, which is why it suits a harness-worn connector rather than a heavy-duty rigging application.

What connects to the Bm'D?
Any compatible lanyard, rope grab, SRL, or anchor strap with an opening rated for this carabiner’s gate size — check the connecting device’s own listing for its rated connector dimensions.

Is this compatible with any harness?
Yes — it clips to a standard harness D-ring; confirm your harness’s D-ring opening and rating are compatible with the Bm'D’s gate before ordering.

What's the difference between the Bm'D and the Petzl EASHOOK?
The Bm'D is a traditional locking carabiner with a round or D-shaped gate; the Petzl EASHOOK is a gated open connector built specifically for Petzl’s Absorbica and ASAP’Sorber lanyard systems. Pick based on which hardware your setup calls for.

Is the Bm'D OSHA compliant?
As a connector it forms part of a compliant fall arrest rig when paired with a rated lanyard or lifeline, harness, and anchor under OSHA 1926.502 — the carabiner itself is a component, not a standalone compliance item.

Do I need more than one Bm'D per worker?
That depends on your system — a twin-leg lanyard or a setup with a separate anchor connector may call for two; a single-leg lanyard typically needs one at the harness end.

How do I inspect the Bm'D before use?
Check the gate opens, closes, and locks fully with no binding; look for cracks, deformation, sharp burrs, or corrosion on the body and gate; confirm the locking mechanism engages every time. Retire after any fall arrest or if the gate doesn’t lock reliably.

Can I use this with a rope grab or SRL?
Yes, provided the rope grab’s or SRL’s connection point is rated for this carabiner’s gate size — confirm compatibility on both product listings before ordering.

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

Does the Bm'D replace a snap hook?
It serves a similar connecting role but as a locking carabiner rather than a spring-gate snap hook — choose based on what your lanyard, rope grab, or anchor strap is rated to accept.
