The Kramer WP-20-BLNK(W) is an alternate cover plate for the US-D size WP-20 Wallplate Transmitter that provides an opening for the HDMI connector, and covers the Ethernet connector.
Please Note: The WP-20-BLANK plate covers the RJ45 Ethernet port on the WP-20 Wallplate but leaves the HDMI, VGA and 3.5mm ports exposed. Think of it as protection for unauthorized connections to your network infrastructure.
