Metal Tube? 30cms or longer x 5cms (South Cadbury)

If you’re clearing a garage or workshop in the coming weeks don’t throw away that bit of metal tube 🤩 My rotary washing line took off in the high winds a few weeks ago so I need to fix it in the ground better. So if anyone has a bit of scaffold pole or metal tube about 30cms or longer and diameter 5cms this would do the job for me. A housewife needs to do her washing so I’m sure you know how important this is 😉😉😂
