The upper portion of the lid hinge can be easily detached from the lower hinge, which helps support the use of our Charcoal Rotisserie Kit accessory (part # 2290). The design is meant to have a degree of natural movement. This won’t negatively impact the function of the grill.
Also, it’s important to remember that the lid and bowl are coated with a porcelain enamel, and if the hinge was completely rigid, there would be a risk of damaging the enamel.
