Hi Mark! We gave up on 4x4s some time ago as they are too hard to guard effectively. Instead boxes are mounted on conduit with a 4 inch ,solid septic/drain pipe over that and well off the ground. A cap is drilled for the conduit diameter and held in place with a hose clamp. The 4 inch pipe is then elevated to meet the cap and secured with 2 to 3 screws. Makes a great predator guardian we no longer have problems.
