Unless your deer guard will be placed in a pristine environment, it is likely to gather leaves or other road debris over time. To insure the effectiveness of your deer guard, the cavity below the top surface should be maintained and cleaned out. A cleanout on your deer guard provides for a portion of the top surface to be removed without having to pull the entire guard off the footings. By removing a portion of the top surface, access to the cavity is made easy. Cleanouts are bolted in place. Cleanouts are not available on U-80 Deer Guards.
