VAR = 3 3/4 x 3 3/4
We have installed our Arbor in High Wind areas with the Oversize Anchor kit shown above. It is rated to withstand winds of up to 110 miles per hour. The recommended installation is to dig a 12" x 12" hole that is 30" deep and place a significant portion of the anchor in concrete underground as shown in the drawings below. For best results, we recommend doing the concrete work at least 3 days ahead of the Arbor install so the concrete will cure prior to attaching the Arbor to it. You then place the wood posts in the cradle and bolt the wood to the anchor. We supply wood trim pieces to hide the metal hardware completely so the bottom of the posts looks like they have a wooden boot around them when installation is complete.
Notes:
- If your Arbor is placed in a snow area, the concrete must be 6 inches below the frost line
- At least 2" clearance between edge and steel to be filled by concrete
