What is a Chain Link Butterfly Latch?

A Butterfly Latch is a spring-loaded, self-latching gate latch designed for use with for chain link swing gates.  They are easy to install and operate, which makes them popular for residential fences, particularly chain link pool fences when used in combination with spring gate closers.

How Does a Butterfly Latch Work?
When the gate makes contact with the latch, the momentum of the gate lifts the angled front end of the latch up, opening it.  The gate then hits the back of the latch, which stops its forward momentum.  With nothing to hold it open, the springs in the latch quickly close the front end so that the gate cannot swing back out.
