I found instructions for this pot rack in some building magazine, I forget which. It's really easy and very functional!
You will need:non-stripping screws (about 2" or 2 1/2" long), I like dry wall screw that are black
2" x 4" however long your space is, mine was about 60", make sure it is not warped, pre-paint if desired.
plumbing pieces:
2- flanges 1"
2- connector pieces 1" diameter (Ithink they are about 2" long)
2- 90 degree corner pieces 1"
1- long piece 1" for pots to hang off of, whatever the length of your wood piece is go down about 3-4 inches
6- S-clamps or S-hooks 1"
All of these things can be found at your home improvement stores, sorry about not knowing the exact names, I never do!
To Make:1. position wood where you want it, make sure it is level, mark top with pencil.
2. pre-drill some holes into your wood (I did 1 under the center of where each flange was going to go so that the screws were invisible)
3. match wood up with line drawn earlier, drill screws through the 2 holes ( you may need an extra hand to hold up while you screw). Now your wood is in place, check again that it is level, adjust if it is not.
4. The instructions I used said to use a vice for twisting the plumbing metal parts together. Don't worry about twisting all the way, mine are only twisted about half way and I only used a vice for twisting parts of it. Put all the metal pieces togehter as in the picture, make sure flanges are both completley flat facing the same direction.
5. Position flanges on either end of wood, evenly spaced from sides, measure a distance from the top of the wood and make sure that both flanges are exactly the same distance, then mark holes of flanges with a pen. Remove flanges and pre-drill the holes. Screw flanges on.
6. Now add you S-hooks, if necessary you may need to tighten the part of the s-hook that attaches to the pot rack, if so you should do this on a vice before putting rack on wall. I didn't need to tighten mine, I wanted them to be able to slide.
Hope the instructions are clear enough!
