Where can I buy magnetic pushrod connectors?

[Wax Savage]

Hi guys,
I have performed many internet searches to locate a source for the magnetic pushrod couplers I see being used in various sub builds but, without luck. For all the subs I see sporting these connectors, it's weird I have not found a source. Would some of you direct me to a website to buy them?

Thanks!

You can also try this, you can get it from the orange big box store.
just drill or poke a hole at the end.
