Thermostatic 3 Axis Valve Set integrated with a T Piece (for installing a towel rail as Dual Fuel) specially designed for installing at the corners of a radiator with pipes coming through the wall and a flush fronted finish where the TRVS will not protrude forward, Left Sided. These can be seen in some of the lifestyle shots of Terma radiators - so this is the accessory needed to achieve that look. 3 Axis (corner) orientation and left sided (so valve sits on the left hand side of the product with the TRV head reaching out to the right in line with the bars). Chrome in colour.
