S Brand Plug

Hey guys, I just got a new 600 watt magnetic ballast but it came with a socket already wired directly to it. So, I though about wiring my cool tube directly to it but it would be a bitch to run into my tent, etc... Do any of you guys know where to find the S brand plug to wire directly to it? Not the adapter.
Thanks,
Fu
New Ballast

Type of Plug I'm looking for

Bump, could really use this for next grow coming up. Anyone?
