did 2 34' singles last week. great video and great points. also they are HEAVY!
Great video! Maybe in the next video you can go over what is needed for the support posts for this system to perform well. Definitely fewer posts needed compared to sliding gates but much heavier duty.
Square vs round post
Very informative. Good video presence by Joe.
Thanks! I appreciate you watching and weighing in!
Hey Joe, thanks for another great video. Do you deal with barbed wire ?
Awesome video Mr. Joe!
Thank you, sir!
🔥video good sir. Cantilever gate is exactly what I need on the acre lot. Never knew they existed.
Always happy to help, we really like to employ cantilever gates whenever possible!
I've been in the fencing business for 10 years and I think you did a great job explaining the cantilever gates. We do a lot of cantilevers. Living in a northern climate they do work better in the snow. Swing gates next to the road almost always need to swing in so they don't interfere with the sidewalk/street so you need to be on the inside of the fence to shovel it away. If the gate is installed as low as that was however, the bottom rollers can be encased in ice which makes moving the gate nearly impossible. We make sure to remind customers that the bottom rollers need to be kept clear. When we make our gates we make the gate 1/2 the opening + 1' but set the back post at 1/2" the distance. If you don't, when people slam the gate the back rollers get hit and can twist over time. Once they get out of line, they apply friction to the top and or bottom rail and again, make the gate difficult to move. Using an operator eliminates that thought. I enjoy your videos, you know your stuff.
Great points! Appreciate you watching and weighing in!
What about the safety of the neoprene rollers? are they as safe as the metal ones. Also this would be a long term install for me. Should I worry about decoupling at all. Like can the fence fall on someone and maybe I should add an extra post and rollers for safety
Thank YOU ! good work up. . . .
You’re very welcome, I appreciate you watching!
🙋🏻♂️ ..might you suggest a manufacturer for those particular rollers?
How do I get in contact with you I’m a welder and fabricator and I’m looking to start my on fencing company I worked for a fencing company and have all the experience required to build al them gates but I do not know where to start would you help?
Thanks

Very welcome, always happy to help! Thanks for watching!
Do they put chain link fence on the part of the gate that will not extend in front of the opening?
Very nice gate. I'm going to try and install one for myself after my welder welds it together. Question: How much post is over the gate to install the top roller and how wide does the post need to be for a gate opening of 12' with a gate total of 18'?
You should leave the posts about 10" high so you have lots of room to install your top rollers over the gate. The higher they are, the move adjustment up and down you'll have. I also like to install my top rollers turned to the outside of the fence and somewhat loose. Then you set the gate on the bottom rollers and quickly swing the top ones around and down on the top roller, leaving a small gap between the roller and rail. If you have an 18' gate, your second post is spaced 9' from your first post. Make your gate a total of 19'
What are my options to automate a cantilever gate? Is a motor with a chain/belt the only option?
In the regions of the country that have major snow events (measured in feet rather then inches). would you need to build a shed for the gate to retract into to ensure reliable or emergency operation?
I don’t know if that’s necessary, I’ve seen cantilever gates work reasonably well up in Canada.
Question for you.. I just had one of these installed. It appears to me they installed it upside down? On almost all images i see of these kinds of gates, the angled pipe sections are going upwards towards the ends of the gate. Mine go downwards.. is this an issue i need ot have addressed? so for a 20 foot openeing, a 30 foot gate installed mine looks like this [ / / / | \ \ ] and it should looks like this correct? [ \ \ \ | / / ] if that makes sense. The 3 lines is the opening and the 2 lines is what stays inside the roller section.
Technically yes. However, since everything is welded together it’s less critical than say a wood gate.
Am very interested in a sliding gate. What kind of sliding gate works on a hill? Cantilever or Wheeled or other. We don’t have the room for a tradition open into or out of property gate as we have a small driveway that opens onto a public community driveway. So sliding gate is our only option. Also we have deliveries and need the wide open space trucks require. However the downhill grade may be a factor in design. I have seen cement posts constraining the gates that slide over like a cantilever but have an attached spring wheel that keeps contact with the ground. Hummmm?
Two gates installed in Springfield several decades ago that would be for a good topic are the back gates of the federal court house, or the loading dock gate at Southwest Power Administration off Battlefield and Golden. Actually now that I think about it, there are several big sliders in the area. I doubt they would allow it, but the big ones are the Springfield Underground at the North entrance or the chain link variety is the far east entrance to Regal Beloit on Mustard Way.
couple side notes, we found the best ratio for wind and weight balance 60/40. 60% of the gate is suspended when at full close. 40% behind the front wheel to brace the gate in the wind.
Funny story about the ice you described. Dad installed those gates behind the court house... 25ish years ago. About a year after we had about an inch of ice come down and lock up the gate. Before calling my father, one of the courthouse employees decided to take his attempts. Started with a hammer, crow bar, torch, ended with him wrapping a chain around the far side and attempting to pull it with his truck, Promptly removing his rear bumper. When we arrived the gate was off its track, all four rollers were broken, the brackets that held the wheels were torched off, the operator was crushed and all the wiring was damaged below the concrete pad. Back then the rollers didn't have covers, but there were adjustment bolts in the roller height brackets. A 30 second adjustment could have saved them tens of thousands of dollars in repair.....
Wow well that’s a good video!
Question: I live in Hawaii (I know, congratulations!) I currently have a fence and would like to transform into one of those gates! I’ll look into it!!! Thanks. (Assuming you don’t serve in this state?!)
I wish we did!
Would be more useful if he told us the pros and cons of a cantilever vs a track sliding gate
Not mentioned, but integrally important, the angled bars switch direction depending on which side is cantilevered in order to take the stress by pulling tension towards the opposite end so If one were to place gate upside down it defeats the purposes. If a welder label top side and outside for installers!
Great point, I appreciate the addition!
I'd like to see the actual mechanics of how the gate is able to cantilever. The only thing I can think of is there is a roller on the bottom at the open end and a roller on top at what would normally be the hinged end.
Noted, we’ll add it to the video production schedule!
I've seen cantilever gates with the tail end sloped. That results in less material for counter balance. Does this mean a sloped tail needs to be longer than 50% of the gate or is 50% still sufficient?
Hmm, I haven’t seen one but I would assume the tail would need to be longer since there is less mass counter-balancing the gate itself!
@@JoeEverest its all about the distance between the rollers. if the gate is 7m long the distance between rollers should be at least 2.3m.
How do you install them what's involved
Great question, I'll add it to the video recording calendar!
Rather than the 'extended fence' ballast set-up. To reduce the overall gate length, have you considered the likes of water ballast for the counterweight?
I’m really not sure how that would work on a gate like this, considering it would need to be counted weighted on both ends.
How far apart do the posts with the rollers have to be?
Half the gate opening.
Let’s hear about vertical pivot gates, pros and cons.
Agreed
Can't say its more expensive, swing gates need motors both sides, and the work associated with those motors can be extensive.
You never showed how it works.
It’s on the recording board, just have to get to it! Sorry, I totally overlooked the fact that they’re not common in other areas!
Thank you so much for the great video. Here's a question for ya! What types of 'gates' can be used for a cantilever style? Let me explain better what I'm trying to ask. Say, you want to do a barn door in your house. You could buy just a blank slab and turn that into your barn door, it doesn't necessarily have to be labeled as that. So could gates of this type work in that manner? Could I just find any gate I like, and turn that into a cantilever style? Like I could with a blank door slab/barn door type. Ha ha. Thanks.
