Tube selection here is organized around fit and structural protection. Use filters to narrow by diameter (commonly 1.5"–5"), length (from short tubes to 60"+), wall thickness/gauge (e.g., .060–.080), and end style (crimped end vs. end caps). These controls help prevent crushing and keep rolled items from shifting.
