Standard Unflanged Guards

Standard unflanged guards cover belt or chain drives with similar sized sheaves or sprockets.

Standard unflanged machine guards are useful for applications where clearance for mounting is minimal.

The unflanged guard tabbed backplate is connected to the guard with extruded u-nuts through the side of the guard.

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.
