Ha! I have an extra yellow cargo strap, now I know what I'm going to do with it :thumbsup5:
Super easy build:-)
This stuff is so cheap in China, I don't mind building stuff on a spur of the moment thing. I got a 1.5m alu rectangular profile, the scale, some bolts and the cargo strap (thanks for the proper name) and made it in an hour.
I've since taken a tape measurer and added to the alu profile in case I need to see elongation, too.
Here are few more snaps:
