Side guides are used to help to locate the loading the workpieces sideways (as regards the clamping force) while loading, either manually or using a spring guide.

This type of side guide can be kept in place while machining, or if the side of the workpiece needs to be free to be machined, then the side guide can be taken away or flipped down in some cases.

RMG-M1 is a combination of side guide RMG-1 and magnet M-1.
