The #5315 balusters are good quality and were delivered primed as ordered. However, my suggestion before you order... Be sure you confirm all measurements. The pin top diameter on the 5315 is not listed in the product description, my bad for not asking. The diameter is 7/8"; other pin tops are 3/4". This may not be a big deal on new construction, however my project involved replacing the balusters and reusing the bannister (that was already in place). The existing holes were drilled for a 3/4" pin top. Bummer... Tom was helpful in reordering #2015 and I ended up with a large (74 balusters) donation to Habitat for Humanity. Lesson... Measure twice and order once.
These were just what I needed. Made my project great.
