Review on Automatic Self-Locking Gate Latch - Heavy Duty Post Mount Gravity Lever Lock for Wood/PVC Fence Gates - Secure Pool, Yard, Garden - Steel Construction - Black Finish - Includes Fasteners Hardware by Brian Diaz

Bought two to replace the two originally installed on my fence. The original ones that got installed were cheap aluminum fasteners that were worn and just plain old. They are made of steel and appear sturdy. I don't think I'll ever need to replace them. I had to take one apart to turn the locking mechanism the opposite direction to get both of my gates opening inwards, but it was pretty easy. They seem to last quite a long time.
