DBI SALA 6116540B Lad-Saf Cable Sleeve with 2000112 Carabiner

DBI SALA 6116540B Lad-Saf Detachable Cable Sleeve with 2000112 Carabiner

The DBI SALA 6116540B Lad-Saf™ Detachable Cable Sleeve is a mechanical fall arrest device engineered for fixed ladder vertical safety systems in extreme industrial, marine, and offshore operating environments. Engineered for mobile deployment along vertical lifelines, it travels freely along the cable during standard ascending and descending operations without requiring manual assistance.

Equipped with an integrated 2000112 auto-locking steel carabiner, the 6116540B establishes a direct, secure linkage between the user’s front sternal D-ring (harness) and the fixed cable system. The mechanical assembly utilizes a dual-cam inertial locking mechanism engineered to clamp immediately onto the lifeline cable during a fall event, dissipating arresting forces to stay well within regulatory safety thresholds.

Model Details

• Manufacturer: 3M Fall Protection (DBI-SALA)
• Model Series: Lad-Saf™ Vertical Fall Arrest Systems
• Manufacturer Part Number (MPN): 6116540B
• Sub-Assembly Components: 6116540 Detachable Sleeve + 2000112 Self-Locking Steel Carabiner
• Condition: New (Original Factory Packaging)

Key Features

1. Hands-Free Vertical Articulation: Automatically tracks operator movement up and down the vertical lifeline, eliminating manual line handling during ladder transit.
2. Dual Independent Locking Cams: Cam-actuated inertial locking triggers instantaneous mechanical bite during rapid velocity drop profiles to arrest falls immediately.
3. Foolproof Anti-Inversion Cam: Built-in physical lockout mechanism mechanically rejects upside-down installation onto the carrier cable.
4. Integral Energy Management: Cam and linkage architecture absorbs kinetic energy during fall arrest, mitigating peak impact shock loads transferred to the worker.
5. Pre-Assembled Triple-Action Carabiner: Supplied factory-fitted with high-strength alloy steel 2000112 hardware featuring a 3,600 lb rated gate.

Frequently Asked Questions

Can the DBI SALA 6116540B sleeve be attached or detached anywhere along the cable?

Yes. The 6116540B is a mid-point detachable sleeve. It allows the climber to install or remove the unit at any vertical point along an unloaded lifeline without having to thread the sleeve from the top or bottom terminus.

Does the 6116540B connect to the dorsal or sternal harness D-ring?

Per ANSI Z359.16 standards and manufacturer instructions, the attached 2000112 carabiner must connect exclusively to the frontal (sternal) fall arrest attachment point on an approved full-body climbing harness, never to side work-positioning rings or rear dorsal rings.

What is the purpose of the anti-inversion feature on this sleeve?

The anti-inversion lock is a passive safety mechanism that physically prevents the internal cam mechanism from closing onto the cable if the sleeve is positioned upside down. This eliminates accidental reverse installation during pre-climb setup.

How often does the sleeve require recertification?

A formal competent person inspection must be performed and logged at least once every 12 months. In harsh marine, caustic chemical, or offshore operating conditions, inspection intervals should be shortened to quarterly. The sleeve must be retired immediately if it has arrested a fall.
