The Monument Thin Jaw Adjustable Spanner in 150mm size is the compact solution for precision work in tight spaces. This smaller variant is perfectly sized for close-quarter plumbing tasks where manoeuvrability is essential, making it ideal for working inside confined cabinets, behind radiators, and in cramped bathroom installations. The slim-profile jaw design provides exceptional access to fittings, tap cartridges, and nuts that would be impossible to reach with standard spanners. At 150mm, this spanner offers excellent control and precision, particularly when fitting or removing radiator bleed valves and accessing tap cartridges where the complete removal of the shroud is not possible. The adjustable jaw mechanism accommodates various fitting sizes whilst maintaining the thin profile that makes this tool so effective in restricted areas. This compact size is particularly valued by plumbers and heating engineers working on domestic installations. Features and Benefits:150mm compact
