Hi guys

I'm looking for something like this that can be cemented into our driveway to prevent an outward opening door being ripped out of our hands in the high winds. 
Needs to be cemented in so needs to be substantial. 
Thanks

You may find it difficult to mount the post you are looking at without it being a trip hazard.  How about an overhead door closer with hold open?

It is a good idea to have the stop at mid height of the door. By doing this the door is not distorted, as it is when the bottom of the door crashes against the buffer. The centre of a blank door usually has a structural section at mid-height, but aim for another horizontal bar to suit your door.

The height also prevents the post from  being a trip hazard.

 

In simple terms it can be any sort of post with a doorstop fixed to it horizontally.

If this was a rear service door then it can be as functional as you like: a 2x2 timber will also flex when hit so is good for the door. A scaffold tune is firmer. Then work up from there to something prettier as appropriate to the location.

Thank you for your helpful, detailed reply. Given us plenty to think about. We are now looking at bollards rather doorstops!
