These are NOT full extension slides. The photos in the ad are very deceiving. Read carefully because when you do, you'll find that you only have 2.1 inches of space to open the drawer. The photos in the ad show the slides fully open and fully extended (double length). See the attached image for the actual slide fully open. If a 2" drawer opening is enough for your project they will work, but if you need more than 2" don't waste your time/money. Also, no installation instructions or mounting hardware are included.
