Ideal for elevated construction, telecommunications towers, and industrial maintenance, this self-retracting lifeline is rated to support up to 310 pounds, including tools and gear. Users often ask whether the galvanized cable resists corrosion in harsh environments—yes, it’s built for long-lasting reliability even in outdoor or high-humidity job sites. The 3M DBI-Sala Smart Lock SRL also meets stringent OSHA and ANSI standards, ensuring compliance and peace of mind for safety managers. Whether you’re upgrading fall protection for crews working on bridges, oil rigs, or power plants, this SRL provides the trusted safety performance professionals expect from 3M. Available from Enviro Safety Products, an experienced U.S.-based distributor of certified PPE, this self-retracting lifeline represents a smart investment in worker safety, productivity, and regulatory compliance.
