Magnetic Cylinder Squares
Suburban Tool magnetic cylinder squares provide a precise, self-standing reference for checking squareness and perpendicularity on the surface plate. The cylindrical form gives a true 90-degree reference in every direction, while built-in magnetism helps hold the square and reveal light gaps against the part.
Machinists, tool & die makers, and QC/inspection teams use a magnetic cylinder square as a squareness comparator to check parts, fixtures, and machine setups. Available in 4", 6", and 12" heights, this collection covers a range of inspection needs. Made in USA.
