I've no idea about street sweeper bristles, but the length is probably quite consistent as they should break off at a similar point. Ask Quicklocks for some info/samples, as he says he has an inexhaustable supply.
Go to "Buy sell trade" and check out 'Free street sweeper bristles'.
HTH.
If it ain't broke.....pull it down and see how it works anyway!
Hey,
I'm not sure about where you live.
But the Australian bristles are 2.5mm wide.
Length varies depending where they snap off, but generally about 15cm.
Sorry I dont have any pics.
Hope that helps.
