Extron WPC 210 A MK (part number 70-990-03) — the MK-format version of Extron's one-gang pass-through wallplate, carrying HDMI, VGA and 3.5 mm stereo audio into an MK junction box.

Functionally this is the same plate as the EU variant; the difference is the box it fits. MK junction boxes use a slightly larger one-gang footprint, so this model measures 3.38 in. square against the EU model's 3.17 in., with the same 1.97 in. depth. Signals are handled identically: HDMI in and out on a pigtail, VGA and analogue audio broken out to captive screw connectors for permanent termination. Video follows HDMI 1.4 with a 10.2 Gbps limit, which supports 4K and UHD at 30 Hz in full 4:4:4 or at 60 Hz once chroma drops to 4:2:0.

Key Capabilities

• Designed for one-gang MK junction boxes, 85.9 x 85.9 x 50 mm envelope
• HDMI, VGA and 3.5 mm stereo audio pass-through on one metal plate
• Up to 4096 x 2160 at 30 Hz (4:4:4) or 60 Hz (4:2:0)
• 10.2 Gbps maximum video data rate, 3.4 Gbps per colour
• Captive screw termination for VGA and audio; HDMI on a pigtail
• 0.2 lb (0.1 kg) plate; needs 1.85 in. clearance inside the box

Where It Is Used

Installations built on MK junction box hardware — teaching spaces, boardrooms, training suites and healthcare meeting rooms in regions where MK is the wiring standard. Like the EU model, it is chosen where HDMI and legacy VGA must coexist and audio needs its own dedicated path.
