How to Choose the Correct Scaffold Extension Frames
Identify the component by more than appearance
Scaffold Extension Frames are presented here as part-number references for scaffold owners, contractors, and qualified configuration reviewers. Available product information includes names, codes, listed dimensions, and explicitly named scaffold families, but a matching photograph, color, or general shape does not prove that two components are interchangeable.
Part number and component role
Confirm the exact part number and applicable manufacturer configuration before using a frame in either orientation. Record the complete marking exactly as it appears, including prefixes, suffixes, hyphens, and underscores. Confirm the component's documented role; similar-looking parts may connect differently or belong to a different system family.
Information needed for a compatibility request
- Complete part number and system family
- Component type and installed location
- Nominal and measured dimensions, with units
- Connection or hook details and identifying finish
- Clear photographs of the full part, labels, and both ends
- Required quantity and shipping ZIP code
