The WILLIAMS COMFORT PRODUCTS 2-302-16-2-0 is a three square file measuring 6.25 inches in length with a smooth cut finish. Three square files feature a triangular cross-section that makes them well suited for filing interior angles, cleaning out corners, and deburring threaded components. The smooth cut rating means finer tooth spacing, which produces a cleaner surface finish with less material removal per pass. This file is appropriate for use by electricians, HVAC technicians, plumbers, and general trade professionals who need precision filing work on metal parts during installation or service tasks.
This three square file is used in trade applications where access to tight interior angles or V-grooves is required. Common tasks include cleaning burrs from cut conduit, refining notches in sheet metal, and dressing worn threads or keyways on mechanical components. Its compact 6.25-inch length makes it manageable for close-quarters work that longer files cannot reach effectively.
Designed as a general-purpose hand file compatible with standard filing tasks on ferrous and non-ferrous metals commonly encountered in HVAC, plumbing, and electrical trade work.
Hand files are used by trade professionals without power and require no special installation procedure. Wear appropriate eye protection and gloves when filing metal components, as sharp burrs and metal filings present a laceration hazard. Always secure the workpiece before filing to prevent movement and ensure controlled strokes.
