- Half-rack width, 1U; two fit side by side with the RK-1 adapter.
What the manufacturer doesn't say
- Kramer publishes no vulnerability reporting page that could be opened on 30 Sept 2026, so security_support has no vulnerability_contact.
- Consumption is given only as 265 VA.
- The mains inlet type is read from the drawing, not named in text.
