3M DBI-SALA 7241422 Tension Absorber for 8 mm Horizontal Lifeline

The 3M DBI-SALA 7241422 is a tension (energy) absorber for 8 mm horizontal lifeline (HLL) systems. It maintains correct cable tension and absorbs energy in a fall, reducing the peak force transmitted to the anchors and the worker, which keeps the whole HLL system safe and within its design limits.

Product overview

A horizontal lifeline lets one or more workers move along a span while staying tied off. The 7241422 is the in-line absorber that sets the working tension (0.8 kN) and dissipates energy during a fall, limiting the peak force to about 11 kN. It is a core component when designing or assembling an 8 mm DBI-SALA HLL.

Key features and benefits

• Energy absorption: dissipates fall energy to limit peak load on anchors and the user.
• Sets cable tension: establishes the correct 0.8 kN working tension for the line.
• For 8 mm HLL: designed for 3M DBI-SALA 8 mm horizontal lifeline systems.
• Compact in-line unit: about 24 in (0.6 m) installed length.
• Genuine 3M DBI-SALA: engineered as part of a certified HLL system.

Main industries and applications

• Construction & steel erection: spans where workers move horizontally at height.
• Oil, gas & petrochemical: pipe racks and process structures.
• Transport & logistics: loading bays and vehicle-top access.
• Utilities & infrastructure: bridges, towers and walkways.

Frequently asked questions

What is the 3M DBI-SALA 7241422 used for?

It is the tension/energy absorber in an 8 mm horizontal lifeline system. It sets the working tension and absorbs energy in a fall to limit peak forces.

What is a horizontal lifeline (HLL)?

An HLL is a horizontal cable span that workers connect to so they can move along it while remaining protected against a fall.

Is the 7241422 a complete system?

No. It is one component of an HLL. The cable, anchors, brackets and tensioner must be specified and installed together as an engineered system.

Does it need professional installation?

Yes. Horizontal lifelines should be designed and installed by competent persons and inspected regularly. Techmaster can advise on the full system.
