Abstract
A guard adapted for enclosing an exposed return roller in a conveyor belt system. The guard attachment brackets are adapted to utilize the existing attachment point hardware of the exposed return roller to facilitate guard installation on an existing conveyor system. The attachment brackets provide adjustment of the guard relative the return roller. The guard permits visual inspection to detect accumulation of debris between the guard and return roller. The guard may also be adapted with wiper extensions for cleaning debris from the conveyor belt surface.
