Key Features
- Retracting cable takes up slack as the worker moves within the permitted work area.
- A stainless steel braking mechanism engages during a fall; it does not eliminate arrest distance.
- The swivel snap hook includes a load indicator to support inspection.
- The protective housing cover helps shield the unit during demanding jobsite use.
Common Uses
- Commercial construction with suitable anchorage and adequate clearance.
- Elevated industrial maintenance and plant work.
- Bridge or structural work where the planned connection and cable path meet the instructions.
Selection and Use
Before choosing this cable SRL, assess anchorage height, swing-fall exposure, obstructions and the required clearance below the worker. Nine feet describes cable working length, not a safe free-fall distance. Attach each connector in the orientation specified by Miller and verify that gates close and lock without interference.
Standards and Safety
Miller specification SP447 lists legacy ANSI Z359.14-2012 classifications. Those ratings must not be relabeled as ANSI Z359.14-2021 Class 1 or Class 2. This documentation does not establish leading-edge or foot-level tie-off approval. Use the label and instructions for the supplied unit to determine permitted installations.
Employers must select compatible components, provide training and plan for prompt rescue. OSHA 1926.502 addresses construction fall-protection systems; OSHA 1910.140 applies to general-industry personal fall protection. These are employer requirements, not OSHA product approvals.

FAQ
Can this SRL be used over an unprotected edge?
Do not assume so. Confirm explicit manufacturer approval for the edge, cable path and anchorage configuration before selecting it.
What happens if the load indicator activates?
Remove the unit from service and follow Miller’s inspection and authorized-service instructions. Do not reset it or return it to use based only on appearance.
