You can put a dozen hinges on it, the gate will still sag over time. What I have done in the past (very occasionally) is run a guy wire from the top of the post about 5 feet above the gate to the bottom at the far end. It's helped but I ended up having to put in a turnbuckle to make up for the stretch in even 1/4 in steel cable.JSteim":2qmtoggl said:dun":2qmtoggl said:Ours are all hung on 4 inch posts.

I have noticed that as well with the 8" wood posts on other parts of our fence. I am thinking of trying 3 hinges instead of two to see if that helps.
The gates I am asking about will be on a pen of continuous fence panels. The gate post will not have a traditional H brace hence the question on pipe post diameter.
Most of my hinges are welded to the post so they don't turn. The few that aren't; are in holes cut through the posts and tack welded.JSteim":30rlwgjk said:Kingfisher -
The 12' gates are on 50x30 pens. The 16' gate is on an 85x100 pen. Thought is those should be low pressure areas.
For the sorting alley and sweep I have 10' Priefert bow gates which are pretty heavy.

The block under the end of the gate would work. Also maybe one of those wheels that bolts onto the end.
It looks to me like a lot of the sag is the top hinge turning some when the gate gets to 90 degree perpendicular to the post allowing the gate to droop. Does not seem any way to tighten the hinge bolt enough to stop this. My thought was perhaps a third hinge pointed up might support the gate enough that the top hinge would not have any twist. Cheap and fast enough to try in any event.

I'm sure that's a very good option for gates, etc. where all that pipe's readily available.fenceman":1i8d75d0 said:Priefert bull gates are a dam fine product for sure. I've probably hung thousands of em. The 16 footers will sag a inch or two. Their made out of 16 gauge steel. More than adequate for most work. In heavy traffic areas I like at least 12 gauge on the gates. Schedule 40 pipe is better if you got gate post that can handle it.
Where jstein is you can't go for walk without running into a pile of oilfield pipe.

Same gate as above- I hang mine using creosote posts and creosote board bracing -
That gate hasn't moved an inch since I set it in 2005 or '06.
