Wuko 4052 Sheet Metal Maxi Hemmer

The WUKO 4052 Maxi Hemmer is a professional handheld sheet metal hemming tool designed to finish pre-bent edges from 90° to 180°. Specifically developed for long, straight sheet metal panels, the WUKO 4052 creates clean, consistent hems without requiring clearance at the ends of the workpiece, making it ideal for metal roofing, architectural sheet metal, and custom flashing fabrication.

With a bending height ranging from 8 mm (5/16") to 52 mm (2"), the WUKO 4052 allows contractors to form deeper hems along extended sheet metal edges. Its movable counter rollers can be released with a single movement of the handle, allowing the tool to be positioned or removed anywhere along an existing bend. This convenient design improves accessibility when working with long panels or in confined spaces. The tool comes in a sturdy carrying case for convenient storage and transportation.
