Garage related: Wire shelving

[C-10 simplex]

Can you tell me about the wire-type shelving such as this:

http://www.uline.com/BL_3878/Adjusta...-Wire-Shelving


1) My first concern is that this appears to be a product in which it appears that a lot of companies are essentially selling the same thing.

This is similar to the quick-change rear axle----halibrand, winters, speedway engineering, tiger etc.
Also, cragar and weld wheels appear to be similar if not identical.

My point here is i want quality. i feel uline is industrial strength, but i would like to buy locally if possible----i.e., home depot etc.

2) How do the "S" connectors work. How does the modularity/build on thing work.


Actually, why don't you just tell me everything you know about wire shelving?
