Monument 331E Stopcock Key Mini Crutch

About this tool

The Monument 331E is a compact crutch-style stopcock key designed for operating hard-to-reach stopcocks and stiff valves in domestic plumbing installations. This versatile tool provides the leverage needed to turn awkward stopcocks located under kitchen units, beneath sinks, and difficult-to-access outside taps. The crutch end design delivers increased turning force, making it ideal for operating seized or infrequently used stopcocks that require extra torque. The 220mm length offers an optimal balance between reach and manoeuvrability in confined spaces, whilst the hexagon shaft accepts a removable tommy bar for additional leverage when needed. A particularly useful feature is the compatibility with standard socket sets and ratchet handles, allowing plumbers and heating engineers to adapt the tool for challenging corners and tight working conditions. This versatility makes the Monument 331E suitable for maintenance work, emergency shutdowns, and installation tasks where standard keys cannot provide adequate access or turning power.
