Rectangular Unflanged Guards

Rectangular unflanged guards cover a variety of drives, sheaves, sprockets and other moving machine parts.

A tabbed backplate covers the back of the machine guard. Unflanged guards are mounted through the side of the guard and the tabs of the backplate, with extruded u-nuts that ensure fastening metal-to-metal.

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

Additional custom sizes can be easily fabricated. Call our office for more details on fabricated boxes.
