Abstract: A coupling bridge to prevent the accumulation of food products and cooking oils on the sidewalls of adjacent food preparation appliances. The coupling bridge is formed of a steel plate having a top plate with first and second legs downwardly extending from opposed sides of the top plate. The top plate has a width corresponding to a gap between the adjacent food preparation appliances and a width of each of the sidewall of the first cooking appliance and the adjacent sidewall of the second cooking appliance. The coupling bridge is reversible in orientation to accommodate a handedness disposition of the first and the second cooking appliance.
