Aluminum rack ears for RB1100AHx2

Hello,

I have just received an RB1100AHx2 but it’s not new. It has apparently been purchased around July 2015, used for a proof of concept and then sold at good price.

Thing is, I haven’t received the rack ears and screws to mount it in my rack - I guess I have little chance to have seller send them over. Is there a way to purchase the original ones or should I be looking for universal ones?

Thank you!

For the records: Mikrotik sells them as “accessories” now.
