Conveyor guides install onto unpowered (gravity-flow) and powered conveyor systems to control product flow along the conveyor. They include rails, guards, and stops that help items flow smoothly along the conveyor, minimize wear or damage on the items during conveying, and position the items correctly for particular applications. They can be used to direct items along the conveyor, collect and hold items at a certain spot on the conveyor, cushion delicate items during conveying, and prevent items from falling off the conveyor. These products are commonly used on conveying systems in warehouses, package handling areas, manufacturing facilities, assembly lines, and distribution centers.
