The galvanised steel construction uses 1mm thick metal to EN 60670 standards, providing corrosion resistance and structural rigidity for flush wall mounting of AV, data and telecom faceplates.\u003c\/p\u003e\n\u003cp\u003eUsed in residential and commercial installations where multiple AV or data connections need to be grouped in a single location, the double-box configuration allows a small multimedia plate to present HDMI, USB, RJ45, coaxial or audio connections side by side. Each 47mm box includes one fixed and one adjustable mounting lug, allowing the installer to level the box in the wall cavity before the plaster sets.\u003c\/p\u003e\n\u003cp\u003eEach box carries an earth terminal and features a mix of 20mm and 25mm knockouts on the sides and rear for cable entry from different directions. The 157mm x 130mm footprint fits between standard UK stud spacing, and the 47mm depth suits most modern wall constructions including plasterboard on timber studs and dot-and-dab onto masonry. The galvanised finish resists rust in damp wall cavities during construction and over the life of the installation.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e157 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e130 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth\u003c\/td\u003e\n\u003ctd\u003e47 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e25\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_3897646_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are multimedia combination plates?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMultimedia combination plates group AV, data and telecom connections (HDMI, USB, RJ45, coaxial, audio jacks) in a single wall outlet.
