I bought a convection oven, but the width of the cabinet didn't allow for the recommended centimeters on each side for proper ventilation. I bought these heavy drawer slides, attached them to the bottom of the cabinet, and attached the oven to the slides. They pull my heavy oven out of the prep cabinet and then slide the oven back in when I'm done. I use them every day and the oven goes on and off smoothly with a light touch. I highly recommend this product.
