Locate the galvanized steel pipe section, not the black (BLK) pipe section, at your local hardware store.
Determine the choice in pipe diameter. Hold the1/2" diameter pipe up next to the 3/4" diameter pipe. Which would look better in the kitchen? Note: The 1/2" size will be strong enough, even for heavy cast iron frying pans and cast iron Dutch ovens. Threaded galvanized steel pipe comes in different lengths with pre-threaded ends (often referred to as pipe nipples). If the most popular lengths of pipe nipple (16", 24" and 30") are not stocked, ask the salesperson to cut a pipe to the length of your choice and have both ends threaded. The shorter pipe nipples are often found in a variety of popular lengths (2" to 12"). Select two short galvanized pipe nipples that match the depth measurement away from the wall. It's easy to get confused and overwhelmed looking at a seven-foot display rack of galvanized plumbing supplies, packed in small boxes. Take your time. Be mindful to match the galvanized floor flanges and galvanized 90-degree elbows with the chosen pipe-size threads. Grab a bag of wood screws for the flange attachment into the wall stud(s) and a bag of wood screws for the drywall attachment. Near the screws, you will find ribbed plastic anchors to insert into the pilot holes you drill into the drywall. S hooks will round out the shopping list.
S hooks come in different sizes, both in length and hook opening width. The 2 1/2" and 3" S hooks open to fit the 3/4" galvanized pipe without any modification. The 2" S hook opens to fit the 1/2" pipe. If a smaller hook is preferred, the S hook can be modified and opened to accommodate the pipe size using a table vise and pliers. Be careful not to gouge or scratch the S hook with the pliers.
Note: If the kitchen wall space that's been selected has a stud in the middle of the width dimension, there will be a slight modification to the design. Remember, at least one flange must connect to a wall stud. To modify the design, place a pencil mark on center of the wall stud (best estimate). From the wall stud mark, measure the horizontal distance to the right and left ends of the rack. A galvanized T, with three threaded openings, should be purchased. In addition to the galvanized T, you will need three floor flanges, three short pipe nipples of desired depth and two pot rack lengths, both ends of which will screw into the T and respective 90-degree elbows. These two pot rack pipe lengths may need to be cut and threaded at the store, depending on the rack width measurements.
