Homemade coyote rollers

For anyone who doesn’t know what coyote rollers are here is their website, but its basically a rolling pin made out of metal tubing attached to the top of the fence. When the dog (or predator) hits the top of the fence the roller dumps them back on their butt.

Very cool idea, but not cheap. We’ve been looking at ways to top our chainlink fence since Arty has already proved his climbing ability (and for that matter Apollo could go over the fence we have if it ever occurred to him to try). Someone pointed out this page to me. If you scroll about halfway down they describe a homemade “rolling pin” fence topper. Now I just have to figure out the best way to attach it to a heavy duty chainlink fence!


Edit 9/19/2014:  Apparently quite a few people are hitting here, looking at the DIY instructions, and then going onto the Coyote Roller official site and buying.  Because of the volume of people doing so Roll Guard (who owns Coyote Roller) has offered me a spot in their affiliate program, and after some thought I’ve accepted.  What that means for you: if you click through to the Coyote Roller home page via the above links and proceed to buy from them I’ll potentially earn something off of that sale.  I’ll admit that the possibility of earning enough to cover the blog costs was to tempting not to try it.  On the other hand, if you experience a negative experience by doing so, something that appears to be related to the click through, please let me know…..

5/27/18: Not quite sure what happened, as I received no emails, but the original coyote rollers site appears to be down and has been for a while.  There are other places to get them from if you do an internet search for coyote rollers.  I have removed the broken links from this page.

  1. Like you said, it won't be cheap.
    What are your posts topped with?

    Maybe get a buttload of plumbing reducers (that just fit over the top 1 1/2″?) drill them and put a set-crew or thee in each one then drill whatever size pipe that fits the reducer so the cable can slip through.
    Of course you'll need guys on both ends because I'm sure it'll need to be really tight.

    Drill a through-hole near the top of every pole and use an eye-bolt for the cable.

    My problem is digging and the fact that they *know* a farm electric fence only hurts a little for a little while.
    Now we have 120 through a bare wire 6″ above the ground. It's usually off, but plugged in at random intervals.

  2. Did a quick price run up on my local Lowes website, and the pipe and cable should be $70 or so to top the current run. Its the hardware that I'm stuck on, and an eye bolt would work I'd think though I'm not sure my drill is up to the drilling, the plumbing reducers sounds easier if a bit more time intensive. Shall have to play around with it.

  3. Oh, and the terminal post have standard caps on them. But they're pretty big posts, I'll have to measure (I don't even know how easy it is to take off those caps, hmmm). I was looking at the adapters for adding barbed wire, and those would support the body of the rollers, but they're expensive. I'm liking the idea of plumbing parts as a less expensive alternative.

  4. I live in Barbados and my wife and i run a small Boarding and Rescue kennel and would like to know more about this anti jumper roller bar saw the advert of the coyote bar but found that extremely expensive for us since we are both pensioners and can hardly afford the 700.00 US dollars which works out around fourteen hundred Barbados dollars so i would welcome any help in constructing this bar sort of DIY. any suggestions would be appreciated thank you rudi boyce

  5. would like to know more about this anti jumper roller . I live in the Caribbean and would like to hear of any DIY way of making this thing 7000.00 us dollars is way beyond me that would be like fourteen hundred dollars here and that’s without the duty and freight and god knows what else in local charges i am also a pensioner so that’s way out of my pocket range any idea would be welcome. i thought of plastic tubing but i think it has to be something firmer that wont bend with the heat. may also need some sort of ball bearing assembly inserted in the tubing to make it revolve easily with the slightest touch all these things on an island costs much more than on the mainland US so i am waiting to see what thoughts you guys have see if i can make any valid contribution. later thank you. rudy

    • The double layer of tubing acts as bearings. No seperate bearings required. I suppose you could use aluminum tubing if you think the plastic won’t hold up.

    • thanks Ruth will see if i can make that work another idea came to mind could also fill the larger of the tubing with grease that should make it move easily with the slightest touch. just a thought.

  6. So…what hardware did you end up using? That’s exactly where I’m stuck. I have 120 feet of fence to shore up, so the commercial coyote roller is out of my financial reach. I’ve called fencing companies for advice but heard nothing useful at all. Did you solve this puzzle?? Please share with the class!

    • After some trial and error we determined that my little drill will drill through the aluinium posts and ended up using a modified version of the one shown for metal fencing. I think the plumbing reducer idea would have worked easier, but the posts on my fence are commercial grade and thus wider and we couldn’t find fittings to go on them.
