Malco S3R 3-Inch Offset Hand Seamer with Redline Handles | 24-Gauge Capacity

The Professional Choice for Precision Overhead Bending

The Malco S3R 3-Inch Offset Hand Seamer is built for the rigors of field use. Unlike bench-only seamers, its offset handles tilt away from the metal, providing clear sightlines and room to maneuver in tight overhead spaces during HVACR installations, roofing, and siding projects. This thoughtful design helps you maintain edge control while keeping your view unobstructed as you work.

Engineered for Maximum Mechanical Advantage

At the core of the S3R is a compound leverage system that multiplies your grip strength. Whether you’re straightening a flange or flattening a seam, this tool delivers power with less fatigue. It accepts 24-gauge galvanized or mild steel, and its drop-forged steel jaws resist impact while the rust-resistant nickel plating guards against weathering on the jobsite.

• Offset design for overhead work keeps hands above the work surface for better access in confined areas.
• Drop-forged, high-strength jaws ensure durability and clean edges when bending, folding, or flattening sheet metal.
• Rust-resistant nickel plating extends tool life in challenging conditions and workflows.

Precision You Can Rely On

The S3R features precise vee-notched depth graduations in 1/4-inch increments, allowing bends from 1/4 inch to 1-1/4 inches without needing additional measuring tools. The jaws stay aligned under pressure, delivering consistent, straight edges with each squeeze.

• 1/4 inch to 1-1/4 inch bends in 24-gauge galvanized or mild steel for dependable panel work.
• Rigid jaw alignment supports repeatable outcomes across multiple folds.

Comfort That Lasts All Day

Malco’s patented Redline Handles are designed to fit the way you work. Ergonomic contours, soft-touch non-slip grips, and reliable grip performance remain secure even in oily or wet environments. The one-hand operation latch enables smooth transitions between tasks, helping you keep a steady rhythm on demanding jobs.

• Ergonomic Redline handles reduce hand fatigue during extended use.
• Non-slip inserts maintain control in challenging conditions.
• One-hand latch allows quick opening and closing, freeing the other hand for steadiness.

Practical Uses on the Jobsite

From sealing seams on galvanized panels to straightening flanges and preparing edges for a clean finish, the S3R shines in real-world scenarios. Its field-focused design supports overhead work, tight corners, and long runs without frequent tool repositioning.
