Basic, rudimentary, but effective.

If you have ever put together one of those wire shelf units with the plastic sleeves that hold the shelves, this tip may be helpful. Especially if it is already together and you decide to move a shelf in the middle up or down a bit.

You manage to get three corners started, but the fourth simply won't slip over the plastic sleeve as it should. No matter what you try, the fourth sleeves slips out of the little groove and slides down the upright.

Tip: With the three good corners started, but not tightened, use a clamp or a helper to hold the shelf down on the slippery fourth sleeve. Take a 1" open end wrench and slip it under the sleeve and tippity tap it up into the sleeve with a hammer under the wrench. It's a perfect fit on the sleeve.

Simple, but it took me a couple hours to learn it.
