The system consists of 3 components ;
1) wakeman collapsible and telescoping handle net (walmart part # 567048832)
2) bottom half of a sheet music stand
3) cut-to-length broom handle to keep the net open w/ rattle can cap screwed on end, so as not to puncture net with lots of use
Adjust the height that works for you and blast away.
I use it for collecting my pistol cases for reloading, works like a charm.
