Wood fence and gate.

It has to be so when the gate is closed, it closes automatically. So you don't have to push or pull something.

We use the magnetic locks designed for pool applications along with self closing hinges. I don't know the brand. To open the magnetic lock, you have to pull up at the top. this can also be locked with a key.

like this, but ours is a different brand: example lock

We have a wooden fence/gates that we put up when we had a pool. We installed springs to close the gates, and the gates latched with this type of device: https://www.homedepot.com/p/Richelieu-Hardware-4-3-4-in-Gate-Latch-301FBR/202205488?cm_mmc=Shopping%7CTHD%7Cgoogle%7C&mid=sXHAZG02o%7Cdc_mtid_8903tb925190_pcrid_111414437105_pkw__pmt__product_202205488_slid_&gclid=EAIaIQobChMI1OSpn9PN2QIVkLfACh0EtwNdEAQYASABEgKopfD_BwE

You can't open the gate from the outside because these latches are exactly in the middle of the 6' gate - 3' from the top, 3' from the ground, no gap between the gate and the fence.

We used torsion springs and the usual self-latching thumb latches and the city was OK with it as long as the latch was above the minimum height. One gate had a bridle clip on it to make it non-openable from outside.

Look for gate closer spring or just gate closer.

There are also self-closing hinges and pneumatic closers.

Thank you all. I do know about the self closers but I need a decent gate latch. I would love to find one with a lock. Ours have to be set at 58" I believe off the ground.

Something like this one?

Also, check with your city’s zoning or regulation department to see what they allow.

Our fence company used this and I like the way it works.

Some of the suggested locks on this thread will not automatically close the gate when it's opened nor do they require the gate to be unlatched when being opened. That's why a spring or hydraulic closer with a positive closing latch is necessary.

It's also very important that the posts the gate and the lock are mounted on are as inflexible and sturdy as possible in order to minimize subsequent need for adjustments.

Cpartist,

Does anything from Locinox work for you? Another company that I have ordered from in the past which has products from Locinox and MagnaLatch is HooverFence.

Be sure the gate opens away from the pool area, not into it. That way, if by chance the gate is not totally latched, a child or dog cannot lean against the gate and have it open - it is far safer.

I do all my yard gates this way ever since a dear friend who is a dog breeder, had a "breakout" at her house - group of dogs rushed the gate, it opened, they got out, ran a few blocks to the highway and about 10 were killed. It was devastating.

Go for springloaded gate closer and magnetic lock.

FYI Only: Not quite what you need for your pool however I'm using the following for the pedestrian gate adjacent to our development's entry gate. I installed and maintain the electronics. This will also have an additional bluetooth interface for folks who don't want to use keypad plus a bunch of other gizmos I cannot reveal to the public.

Worthy,

I re-read my post, and I'm sorry if you inferred that the lock I linked to would "close" the gate. The description of the lock's "automatic closing" refer's to the lock's mechanism, not the gate.

I want to thank every one of you. I have given DH the links you all provided and I'm going to let him do the legwork on this one. This is one of his domains. He does financial, safety and mechanical and I do design.
