The Bertazzoni 308041 Range Burner Grate Rubber Bumper provides cushioning between the burner grate and the cooktop surface. This rubber component fits beneath the grate to help reduce direct contact with the cooktop and minimize surface scratches during routine use. Installed at the designated contact points under the burner grate, it also helps keep the grate properly positioned and reduces movement while cookware is placed or removed. Replacing worn, missing, or damaged bumpers can improve grate stability, protect the cooktop surface from contact damage, and reduce unwanted noise during use. Checking the part against the range model before installation helps ensure proper fit and positioning.
