3M™ DBI-SALA® Ultra-Lok™ Self Retracting Lifeline

SKU: DS-35044 Category:


Stainless steel working components provide corrosion resistance.

DBI-SALA’s Ultra-Lok Cable Self-Retracting Lifeline comes with a durable glass-filled polyurethane housing and aluminum side plates for maximum durability and minimum weight. For added security, it has an anti-ratcheting twin disc brake system with an audio indicator to let you know it is functioning properly. Stainless steel working components provide corrosion resistance. The swiveling anchorage loop prevents twisting of the lifeline.


The design considerations that went into the Ultra-Lok line of self-retracting lifelines are very comforting. For added security, Ultra-Lok systems have an anti-ratcheting brake system with a visual impact indicator on the business end of the self-retracting lifeline to let you know if it has been impacted. The Ultra-Lok is I-Safe, equipped with ANSI/ASSE Z359.1-2007 snap-hooks, two swiveling connections, and a reserve lifeline, all features that are hard to find on other self-retracting lifelines. This self-retracting lifeline includes an audio indicator known as the “talking block,” which tells users that the locks are functioning properly as the line pays out and retracts.
