Asked by Aurora January 12, 2021

Aurora, thank you for your question. This lock (FM143) will work for both a singe or dual gate. Please check out page 5 in the instruction manual which can be found on the product page about halfway down in blue letters. Open the PDF file to page 5 for installation instructions. One gate will be the master and the other the slave gate. Your opener may need a slight adjustment in the opening speed etc. Our Tech Team can help you set this up, or we do have online videos on YouTube and at our Mighty Mule website. Thank you for being a Mighty Mule Customer.

OC, thanks for the question. Our Mighty Mule Automatic Gate Lock works with the control panel on either your single or dual gate. The control panel works off the battery (which operates the gate) or the solar panel which charges the battery that controls the gate. Thanks

Honestly the lock has been problematic for me on my dual gate. I finally just removed it. At times it would not automatically open or lock causing the gate to stop immediately when trying to open. I just use a rod into the concrete.

Can it work with push button entry/exit control model#132?

The gate lock is wired directly into the Mighty Mule gate opener control box,what ever device is used to open the gate will activate the lock at the same time. The electronics that operate the gate opener also controls the lock. If you follow the owners manual closely and wire the gate lock to the correct terminals it will work.

Make sure you have the red lead connected to the H and the Black wire connected to the L on the two wires that come from the Auxiliary out. Go to page 29 of this manual for the gate. chrome-extension://oemmndcbldboiebfnladdacbdfmadadm/https://www.mightymule.com/wp-content/uploads/Mighty-Mule-MM360-Single-Gate-Operator-Manual.pdf

I wired my lock directly to the wire terminal in the control box and haven’t had any issues. The wire terminal is even marked where you hook it up to.

Installed with Stainless Steel UBolts on a 16 foot farm gate. Predrilled holes to use lag bolts to attach the Receiver latch to a 6x6 Treated Wood Post. Most tedious part of the install is fastening control wire to the gate with zip ties. Some are provided though if you want it to be tidy, you will need more. I bought 713153293662 BLKCBLTIE40P <A> <M> 2.95 4" BLACK UV RESIST CABLE TIE 40PK. Works great.

Tied this into my Mighty Mule opener and works flawlessly. Easy enough to install, but had to buy u bolts to mount to my gate. Simple enough to tie into the opening arm. Holds my gate closed even in the high winds we have had here recently.
