Electrical wall plates are something everyone has a passing familiarity with, but there are many different varieties beyond the usual 1, 2, and 3 Gang duplex receptacles and toggle switch covers. There are also USB charging wall plates; faceplates for VGA, Cat5e, Cat6, S-Video, RCA and BNC connector modules; red engraved plates for emergency use; and weatherproof, tamper-resistant outlet covers.
