There are certain places where rewiring the entire portion is not possible. Tenby Screened TV single is an ideal choice when replacing unscreened socket outlets where rewiring is not a practical solution. This is a full screened non-isolated outlet plate which fits deep 16mm into flush or surface mounting boxes. The screened outlet is perfectly ideal for digital upgrades and a new diecast module achieves high screening integrity without the need for an inner spring fingered cage.
