How? does the shed anchor to the ground to prevent wind damage/blowing away

Thanks for your interest in our products! The Storage Shed does not include an anchor kit because anchoring the shed is optional. The type of anchors needed will vary based on the foundation used. For a wood foundation, we recommend using a wood lag to anchor your shed. For a concrete foundation, we would recommend a Tapcon. For either a wood lag or Tapcon we suggest it measure 2 1/4" - 2 1/2" long and be used with a 1" washer. It is only necessary to anchor in 4 places on the floor of the shed and should be done after the shed is fully assembled.
