This is a replacement pan glide for your refrigerator. The pan glide can be found attached to the refrigerator shelf, and allows the pan to slide in and out efficiently. If your refrigerator pan will not slide in or out of place properly, or if the pan will not stay in place, you may need to replace the glide. There is a pan glide on the left and the right side of the refrigerator shelf. This part is the left side glide, so be sure to determine whether you need to replace the left glide or the right glide. This part is made of white plastic, and is approximately 15 inches long.
