Questions Question: If I buy the removable box option will that take the place of having to build any additional peremiter support. Do I need to build support under the cross support beams. Answer: All the removable is for is so when the guard get a lot of dirt in it it will be easy to clean out ,the guard is lifted out of the box . You my need to put some support under the cross beams if you have loose ground .
