In hardware stores or warehouse the products are place in custome shelf
built with slotted angle posts.
Is there a light duty version for home use?
For example, I want a shelf that is 5 feet wide and 21 inches deep and 4
feet tall with a fix top, and two movable shelves inside. I looked but found
nothing close. Many shelves are 72 inches tall with a joint in the middle of
the posts. I want the posts to be 4 feet with no joint.
Is there a system that has posts of various length, shelves of various sizes
that I can pick and combine?
