When to choose it

Choose the MN236 when the exact instrument requires a 5 mm drive and the adjuster sits deep enough to need the long arm. Read the documentation for the model and confirm the tool seats before applying any force.

The maker excludes the Martin DSS-2018, OMSS-2019, Modern Deluxe series and SC-13E from this wrench’s published fit. Check the exact hardware before substituting this tool for a 4 mm version.
