D&D Technologies ML3TPKA+ML3RPK MagnaLatch Top Pull 20-inch Gate Latch With Round Post Adaptor Kit for Round Posts, Professional-Grade Pool & Child Safety Magnetic Gate Latch, Weather-Resistant, Black

I bought it to latch my dog run gate. The installation was pretty easy, the gap adjustment worked well, and it latches with a satisfying click. Liked the first one so much that I just bought a second one for the main gate. I guess I'll see how often they freeze up in the winter. Edit: After most of a Minnesota winter, albeit an uncommonly warm one, I haven't had any issues with the latch freezing up. We've had snow, freezing rain, -15F temps, and the latch has worked flawlessly through it all.

Once you read the manual and take your time installing it, its great. Comes with all the adapters. If you're not handy, hire someone, we had to get creative to get it installed, but now it keeps our toddler safe.

I love the design of this latch. It is super easy to use even one handed. The handle is in a convenient place. Seems to have a sturdy construction and will hold up well. Looks nice as well. Operating it is simple and straightforward. If new people visit its operation is very intuitive. My only complaint is it seems susceptible to water getting into the mechanism and then freezing causing the lock/latch to stick. Twice now after a rain/snow event followed by extremely cold weather the lock froze. Once in the latched position and once in the unlatched position. To resolve the problem I need to take a hairdryer to warm and dry it. I would suggest thinking about a different lock if yours will be directly exposed to harsh cold and freezing snow/rain.

A need if you have kids and a pool. Works great, relatively easy install and very difficult (too high) for a kid to unlatch.

Workers well on my pipe iron gate. I live in the tropics so I hope it holds up in our strong UV
