Malco 24-Inch Radius Divider for Sheet Metal - Circles Up to 42 Inches

Large-Scale Circle Layouts with Precision

In sheet metal fabrication, small differences can affect fit and finish. The Malco 24-Inch Radius Divider is built for professionals who treat layout as a critical step. Its 24-inch body reaches a maximum circle of 42 inches, letting you scribe large, consistent arcs for ducts, transitions, and custom components with confidence.

Engineered for the tradesman’s realities, this divider balances a substantial feel with quick, on-the-fly adjustments. The fast-adjusting locking mechanism lets you set a radius in seconds and clamp it securely, so you can maintain repeatable accuracy across multiple workpieces without re-measuring.

• Precision layout up to 42 inches; scribe circles and arcs for HVAC ducting, roof templates, and large-scale fabrications.
• Fast-adjusting locking mechanism; smooth sliding action and secure lock ensure quick, repeatable radii.
• Heavy-duty nickel-plated steel; rugged, corrosion-resistant body designed for busy shop environments.
• Replaceable and sharpenable points; resharpen to a fine tip or swap in fresh points as needed for crisp lines.
• Stable and non-slip operation; weighted balance minimizes leg flex and maintains deep marks on treated surfaces.

Real-World Uses

• HVAC ducting layouts that require large-diameter circles or transitions.
• End caps and circular templates for roofing or wall assemblies.
• Custom duct transitions and round tees where diameter accuracy matters.
• Templates for large metal fabrication projects where repeatable circles save time.

This tool is designed as a long-term addition to a layout kit, delivering consistent performance after thousands of marks on cold-rolled steel or stainless. The combination of durability, precision, and ease of use helps professionals plan, mark, and cut with fewer rework moments. While results can vary with material and technique, the radius divider offers a reliable pathway to cleaner, more consistent lines on large-scale sheet metal work.
