The Monument 4501F GRIP+ R2 Three Stepped Radiator Valve Tool is a versatile radiator valve tool designed for fitting and removing most radiator end caps and valves. This professional tool features three stepped sizes to accommodate different valve types, making it an essential addition to any plumber's toolkit. The three-stepped design incorporates 10mm and 12mm slotted fittings plus a 1/2in A/F hex, providing compatibility with the majority of radiator valves commonly found in UK installations. This multi-size configuration eliminates the need to carry multiple separate tools when working on central heating systems. For enhanced versatility and improved access in confined spaces, the tool is designed to work with the MON4537 Shorty Swivel Head Handle or the MON345 Pro Adjustable Basin Wrench. This compatibility allows plumbers and heating engineers to reach awkward valve positions behind radiators or in tight installation spaces where standard tools struggle to operate effectively. F
