Unknown Grasshopper component? Help with identification!

Hello!
I’m just trying to apply this script from the Grasshopper forums but I can’t identify the component type after the similarities, could someone help? I tried opening the ghx. files in the forum site but those files won’t open.
Thanks
Lizzie

It must be a sort of Gate And from a plugin, a Legacy can could do the job.
