Because my gate was compromised from the day I got it, the adjustment has never been perfect. I took time to lubricate everything and adjust it. I hate squeaks, so if I adjusted it so it wouldn't it rattle and squeak, I would have to slam it. If I backed it off to not slam, it would rattle and squeak.Have you tried adjusting so you don’t have to slam?
I don’t have to slam mine for it to latch, it latches very easily.
Mine was cracked when I bought it in 2012. I welded it, and it broke again in about 4-5 years.
It is currently broken again and I need to decide which route to go.
