Seriously a one foot level

what are the fasteners called to mount the steel fence to the vinyl fence?

why do some installers pour the concrete in the hole first then insert the post and others insert the post first?

What are the posts and boards made of?

Lmao mixed concrete on post footing?

Stuff your posts and throw that string line in the garbage.

Videos like this are useless. Gives no information on how far apart to set the posts, how deep to set them, etc.

Don’t do this or follow their procedures
