3M 3900112 Sealed-bloka Galvanized Cable Assembly 130 Ft

Product Description

The 3M 3900112 is a 130-foot galvanized replacement cable assembly designed for use with the Sealed-Bloka self-retracting lifeline (SRL) system. This FAST-Linea cable assembly restores the lifeline to factory-specified performance after the internal cable has been subjected to a fall arrest event or normal wear that necessitates replacement. Galvanized steel construction resists corrosion in wet, outdoor, and industrial environments. Installation is performed by qualified safety technicians or riggers as part of a scheduled SRL service or post-fall inspection and recertification program.

This cable assembly is suited for use in construction, general industry, oil and gas, and utility applications where workers are operating at height and require a compliant fall arrest system. The 130-foot cable length accommodates work at significant elevation, making it appropriate for tower climbing, roofing, structural steel, and similar elevated-work scenarios. It is sold as a single replacement unit and is intended for use specifically with the Sealed-Bloka SRL platform.

Installation Notes

Replacement of SRL cable assemblies must be performed by a competent person trained in fall protection equipment service, in accordance with the manufacturer's service instructions and applicable OSHA and ANSI Z359 requirements. The SRL must be fully de-tensioned and removed from service before disassembly. Do not return the unit to service without completing a full post-service inspection and, where required, third-party recertification. Improper installation of fall arrest components creates a life-safety hazard.
