This vent trim measures 75.6 x 5.7 x 1.3 cm and weighs 227 g. This part is designed for use with ovens and ranges. Your appliance needs a ventilation system so it can properly circulate air. This allows for more even heating and cooking temperatures. The trim is located at the bottom of the cabinet, meaning you will need to take the door off your oven to replace it.
