Just 2 sets. For the top drawer. It has a single one that's worn out so I'm getting a second set to double up the top drawer. But I can get away with 1 set .I also have a Craftsman Professional 46"X24" 13 drawer tool box with the Griplatch drawers that needed slides. I contacted Stanley Black & Decker support and they got me in touch with someone that does Waterloo support and they gave me a quote for the slides. They are $25 per side. With shipping and tax it was $73 for a pair. I needed a whole bunch to rehab an old tool box so it wasn't cost effective. I ended up buying a used Waterloo Magnum top box (like the red one below) and used those slides instead. How many do you need? I attached a pic of a damaged slide and the quote I got and finally the tool box in question.
Update;Thank you I ordered those slides and they fit perfect I put double slides on the top drawer all I had to do was cut off the grip latch bracket for the lower slide.I also have a Craftsman Professional 46"X24" 13 drawer tool box with the Griplatch drawers that needed slides.
