Rated 5 out of 5 by from Easily Done I purchased this gate lock for a 16 foot ranch gate after installing a Mighty Mule gate opener. I noticed my gate could open on windy days allowing livestock or other unwanted things to enter/exit. It was easily installed in just over an hour. Works well and is a must for a secure gate.

Does the latch draw any power when gate is not being opened or closed? Can it be used on a solar only setup?

Asked by: MNGTO
This gate lock does not use any power when the gate opener is in a resting position, when activated to open or close it used 4-5 amps. The gate lock can be used in both settings, either AC or solar.

To follow up on Mavaholic's question about the lock failing (which can happen to any mechanical device, so don't tell us that "the lock will always open": If the lock fails, will it damage the gate openers?

Asked by: Scott VN
TexanSV, Thank you for posting your follow up question. If the gate lock (model # FM143) failed to activate upon gate opening activation the gate opener would attempt to open and then close. This failed opening attempted would most likely cause the gate openers control board to blow a fuse. Thank you!

Is there a magnetic "catch" or other product for the MightMule that simply "pulls the gate" fully closed so my dogs don't stick their head in the gap between the post and the gate and slip through?

Asked by: MickMichael
Hi Mick, the Mighty Mule Automatic Gate Lock uses a latch not magnet to hold the gate panel closed. This lock can withstand up to 2500 lbs. of force, so it should be able to hold in the panel not allowing your pet's to open the gate.

Can this lock be used on a solar 360 opener?

Asked by: Zip2003
Zip2003, Yes it can. However depending on the size of battery you are using to power your gate opener and solar panel wattage you are using you may have to use two 10 watt solar panels to effectively keep your battery charged. Thank you for posting your question!
