This drawer slide rail is for the left side of the refrigerator, and allows the bottom shelf to slide in and out. If your refrigerator door will not close, or the bottom drawer will not slide properly, you may need to replace the slide rail. Make sure the slide rail that is damaged on your refrigerator is on the left side before you select this part. The slide rail is made of white plastic and connects to the side of your refrigerator. It is sold individually, and is an OEM part sourced directly from the manufacturer.
