Abstract: A yoke for a food grade conveyor is formed of UHMW plastic molded as a single unit having left and right upright portions connected by vertically separated upper and lower cross portions. Each cross portion has a stanchion to provide a support face or ledge for connecting to a conveyor runner. The upright portions also include first ledges for supporting runners and second ledges for supporting side rails. The side rails can be screwed into the upper portion of the yoke. Smooth transition regions and curved surfaces promote cleanliness and sanitation. The runners are screwed onto the yokes at the support surfaces, and appropriately shaped stainless steel frame members are screwed onto the yokes. Modified yokes allow the inclusion of lower guides with channels. A flush-top conveyor arrangement is also described.
