The side panels are seamless and mounted to interconnect the inboard end and outboard end walls together. At least one truss extends between the side panels. The side panels cooperating with the inboard and outboard end walls to generally define a rectangularly shaped box for enclosing the carriage and lance tube of the sootblower.
