Where do I find these (pallet hold down clamps)

I'm looking to replace these guys on my press. Aside from the manufacturer (Anatol), where can I buy these? And what exactly are they called?

I have only found anatol to have them. The ones I ordered from Anatol are a different casting than the one you have pictured. I haven't tried them yet but I'm skeptical that they will work better. Just a clunky crappy cast clamp all around.
