Standard Flanged Guards

Our most popular type of machine guard is the standard flanged guard. Standard flanged guards cover belt or chain drives with similar sized sheaves or sprockets.

The backplate covers the back of the guard, which can be attached to guards through holes or brackets made through the flange.

If standard sized guards do not fit machinery, several guards may be re-sized to make a longer or shorter guard.

Note: MGC normal manufacturing policy does not include cutting holes for shafts or making brackets for mounting. This can be done on special orders.
