My husband & I had our deck redone about a year ago, & to finish the job, our contractor had us order enough white aluminum balusters to finish the job -- but we ended up with a slightly different deck size than planned, which meant we've got 4 boxes of balusters (5 per box) left over.
We decided to keep 2 boxes as spares just in case some ever get damaged, but are hoping someone can use the other 2 boxes, since they've just been sitting in our basement.
The balusters are made by Deckorators, & we ordered them online. Here is the listing:
Hopefully the listing has the specs someone would want, but in brief, they are 32" white aluminum balusters, "baroque" which evidently means slightly curved vs. straight, & they are "face mount." Because they are new in their boxes, all hardware that came with them is there, too.
It looks like 1 box (5) is now retailing for $57, & we're selling 2 boxes (10) for about the price of 1 box, so hopefully that is fair.
If there is anything else you'd like to know, just ask -- thanks for looking!
