I bought an Antminer E9 Pro. I currently only have 1 dedicated outlet. The outlet is an L6-20r. What do I need to get to hook this baby up? I can't seem to find a pdu that has an L6-20p with built in surge protection.
Where did you search? a simple google search takes me to this
link Metered-Breaker-Surge Protection PDU, 240V, L6-30P, 30A, 7200watts, (4) C13 & (2) C19 Outlets, Crypto Mining PDU, Data Centre PDU, ASIC/RIGS PDU
This PDU is 7.2kw which is more than enough for your E9 Pros, it has 4*C13s which is enough for the two gears (each miner will need 2 sockets).
