Misc info. on Rockford ballscrews

The factory knows all about these kits.

The distributor knows nothing.
The factory told me all this info in 5 min on phone.
The distributor took 4 days to get this info, with me telling
him every day what he was missing.
I called the distributor to find out if the factory and
distributor would price these kits differently.
Same priceAnd buying from factory is no problem

Last tidbit of information, is when talking to the factory
about custom ends on ballscrews,
They felt the cost would not be to much moreBut of course
needed to see a drawing
