Your local Tractor Supply store would be happy to help you find and purchase this hardware. You can also contact our Tech Support.

    A: HI Mulcrkjim1, we recommend a gate length of 18ft rather than 19.6. That, maybe a bit too long. Great question.

Q: Our gate pipe/panels are horizontal and the lock is too heavy to be mounted on the gate. Can the lock be mounted on the post and receiver mounted on the gate? Basically, the lock will be mounted vertically on the post? Will the lock function properly?

Just what I needed

This is the 3rd gate lock I've purchased and I finally found one / brand that works. It is so nice to have my gate open, shut & lock so that the dogs cannot push the gate open far enough to escape through it. Hurray for the Mighty Mule Auto Gate Lock

Critical accessory for gate

With a little tuning on where the arms rest on closed, this auto lock secures my gate closed automatically. It seems robust and is heavy. I’d add this on again.
