I chose this model based on the previous reviews. If the quality of the grid is correct, other customers were better served than me. This model requires the installation of 4 screws when the grid is to size. Without these screws, the grid will not fit in the oven. Once secured the grid is very stable (more stable than a model without screws). The problem is that the 4 screws provided, 3 are finer than the holes ??? I would refer not because rummaging through my live stock, I found three suitable. Unfortunately, they are longer and so it's a bit ugly. I would not recommend this model. There on the other grids at the same price website (with or without screws) best suited for those who do not want to tinker. I spent time writing this review to you. If you enjoy and that this has been helpful, thank you to let me know by checking YES below.
