Overview The Malco 3-Station Edge Roller (ER3) is designed for bending and forming sheet metal edges across a range of gauges and radii in HVAC, sheet metal fabrication, and related trades. Specification Value MPN ER3 Brand Malco Bend Range 5/8 in – 4 in (15.9 – 101.6 mm) Compatible Gauge Range 29 – 22 gauge (0.36 – 0.76 mm) steel Number of Stations 3 Scale English / Metric (center roller station) Category Pipe & Bar Benders / Sheet Metal Tools Technical Features 3-Station roller configuration — provides multiple bending positions in a single tool, reducing the need to switch between separate tools on the job site. Quick-adjust mechanism spanning 5/8 in to 4 in (15.9 – 101.6 mm) — accommodates a wide variety of bend sizes without time-consuming tool changes. Compatible with 29 – 22 gauge steel (0.36 – 0.76 mm) — covers the most common sheet metal gauges used in HVAC ductwork and light fabrication applications. Precision English/Metric scale on the center roller station — enables accurate, repeatable bend measurements in both unit systems, minimizing measurement errors. Applications Forming edges on HVAC duct panels and fittings in 29 – 22 gauge steel Creating consistent bends ranging from tight 5/8 in returns to wider 4 in edges on sheet metal components Sheet metal fabrication tasks requiring rapid adjustment between multiple bend depths on a single workpiece Job-site use where both English and Metric measurement references are required
