That's how I wire my racks. I use crimpable male copper tabs from RadioShack, crimp the cord to them in parallel, then slide the tabs right into the Flexwatt. The tabs are beveled like a paint scraper so they slide right between the plastic and the metal strip easily. A little solder and a piece of electrical tape and they're done. I finished my 8 shelf rack this way in about 2 hours, from start to heating.
