I had broken 2 drawers in my 40" Husky tool chest and HD Customer Service was unable to find replacement slides for me. I risked it as the price was very good. They arrived the next day and I got to work drilling out the rivets from the old rails and installing these new rails in their place. These rails fit perfectly after I drilled some new rivet holes and now my toolbox is in order again. I couldn't be happier! Those rails hold up great and the 40 inch wide drawers are loaded with tools and you know the drawers are pretty heavy. They glide better than new ones and I'm glad I got the chance to try them. It definitely beats the cost of a new toolbox! I'll order a few more when the next few old slides fall apart again.
