We have two new gate-latches. These things cost around $18 each, but boy, are they ever worth it!
This gate doesn't have one yet; this is how we used to secure all our gates. What a pain, wrapping the chain around a post and fastening it back to the gate.
To open a gate, you just reach for that thingie...
and pull it up. The gate opens.
When you're done, you just give the gate a gentle shove and it locks itself. Amazing! Easy for humans to open, but impossible for animals.
I LOVE my new gate latches, and I love the man who bought them and installed them.
