The following blurb is from the manufacturer, and as it says what needs to be said, we'll let it stand without additional comment.
The 22 is a complete suite of electrical wall accessories that challenges the traditional, tired and ubiquitous cover plate concept. Power receptacles, lighting control dimmer switches, on/off switches, telephone and data connections, cable and speaker outlets, etc. may now be mounted flush into drywall or millwork with a new CSA approved (approved to UL standards by CSA) utility system that eliminates the need for a cover plate. Switches and power receptacles can now be flush with the wall surface and are visually more subtle than ever before.
