Fall-Arrest Carabiner For Height Workers

The 3M DBI-SALA 3100107 is a twin-leg fixed D-ring connector built for fall-arrest systems. Its auto-lock gate reduces the chance of accidental opening while working at height. The gold finish helps the device stand out on a busy harness. It suits technicians who need a reliable tie-off point.

Simple Clip-On With One Common Snag

Attaching the connector is a single-handed motion: press the gate, hook the D-ring, and release to lock. The 3/4 inch gate opening fits most standard anchor points, yet thick webbing or oversized rings can catch on the inner radius. Users should verify compatibility with their specific lanyard before the first climb.

Rated Strength Holds Through Prolonged Hangs

The connector carries a 420 lb working capacity and a 5000 lb tensile strength, so the rating does not degrade during an extended suspension event. The fixed D-ring geometry keeps the load aligned with the spine of the carabiner, preventing side-loading fatigue. Gold coating resists corrosion during multi-day outdoor exposure.

Questions about this item

How can I confirm the auto-lock carabiner is functioning correctly after setup?

Verify the gate snaps shut automatically and locks without manual force, then apply a steady pull up to the 420 lb weight capacity to ensure the 5000 lb tensile strength holds.

What components are included with the 3100107 carabiner and what must be purchased separately?

The package contains the twin-leg fixed D-ring connector with a 3/4" gate opening; no additional hardware or accessories are included, so any lanyards or anchor straps must be bought separately.

Which version of the 3M DBI-SALA carabiner should I choose for my fall-protection needs?

Select the 3100107 model with its 4-19/64" length, gold finish, 3/4" gate opening, 420 lb weight capacity and 5000 lb tensile strength when those exact specifications match your system requirements.
