If your crew is working in saltwater or any moist or dirty location, you need a heavy-duty SRL that can stand up to these harsh environments. DBI-SALA™ offers you the most comprehensive line of sturdy, corrosion-resistant sealed SRLs in the industry—and decades of proven field experience. Our patented, Sealed-Blok™ SRLs keep foreign elements such as grease, moisture and dirt from entering, so your crew can always work with confidence—and at peak efficiency—no matter what their work environment may be. Dual-mode RSQ models are also available that let your crew choose, prior to connection, between fall arrest requiring assisted rescue or self rescue—whatever is most appropriate for your jobsite.
