Fence Post

[jnz01]

I'm trying to fence in the shape of an octagon, is there any way to get the post to the 22.5 angle needed for an octagon. Do you they sell adapters?

Did some searching but couldnt find any 'kits' or hardware for an octagon...except for this..

but this requires more posts...!

What material are you using? If wood, how are you attaching to the posts? You should be able to just mitre the stringers if you are butting them. Of course you would need support blocks under the stringers.

I think that you will find that the angle that you need is 45 degrees, not 22-1/2. Think about it. A square (4 sides) would have 90 degree corners. An octagon ( eight sides) will need 45 degree corners.

But if you going to turn the posts so that they are midway in the corners, then yes, your rail ends will be cut at 22-1/2 degrees.

If the fence material is wood, you would have to cut your rails and toe nail them into a post that would be centered between sections.
If you have a PVC line in mind, you would have to cut the routed holes in the posts and just create the octagon as need be by turning the section the desired miter.
If you are using chain link, that would be the easiest as all you need do is determine your miter , install your top and or bottom rail or coil and then you would install your wire mesh with wrapping the mesh around the posts.
If you are using aluminum, it could be done 2 ways. One very much the same as the PVC line with widening the routed holes on the posts. Two, with using swivel brackets if supplied by the specific line of aluminum fencing you are purchasing.
If you are using steel fencing the same applies as the aluminum.

It would be just my opinion.... a wood fence in an octagon shape would be the easiest to acheive. Second easiest would be the PVC line.

An exception to the rule would be in using post and rail, post and board and or split rail. With the post and rail and or split rail you would have to use corner posts... widening the holes on the posts.
On the post and board you would have to use corner posts as well, but I believe that you would take too much material off the post in order for it to be structurally safe in design. Of course that is just an opinion.

Just curious, what is your plan on the gated opening of the fence. In order to maintain the octagons shape and design you may end up with ganging up on the posts towards the gate. Unless of course you choose to install a double gate opening to suit your spans of each side..?

Good luck

Oh yeah ..

If this is meant to be a railing and not a fence, Most materials come with access to brackets that swivel to suit staircases,up and down and turns miters and corners.

Again, best of luck
