A telescopic shelf is a smooth sliding shelf that allows you to easily and safely check and remove dishes from the oven. They are strong enough to hold heavy items even when fully extended. The oven doors feature 2 layers of glass that keep heat locked inside, providing more efficient cooking, keeping the outside of the oven cool and safe to touch. Each layer can be easily removed when cleaning is needed. DeLonghi ovens and cooktops have been made in Italy for over 65 years. Coming from a long tradition of design and manufacturing excellence, only the finest quality materials are used.
