I purchased these to build adjustable shelves using DIY Diawall and 2x4 lumber. However, I ended up not using them. They have been stored in a warehouse, so there are some scratches, but there are no defects that would interfere with use, such as bending of the posts themselves. For shipping purposes, I will cut the length. This is for 6 channel supports, originally 1820mm, now cut to 1500mm each. (Screws are not included.)
