The WUKO Lok'n'Bak saves your back and delivers the perfect seam! This modern, lightweight seam closer is your reliable tool for closing standing seam panels quickly, cleanly, and consistently—whether on new builds, renovation projects, or long runs.

Practical use

The Lok’n’Bak 0412 is used as a motorized seamer for closing standing seam profiles. Place the device on the prepared panel, adjust the seam height and seam pressure to suit the material, and carry out the closing process in a controlled manner. Thanks to the reverse gear, you can open the front lever, reset it, and conveniently send the device back to the start of the panel – perfect for efficiently working through panels one by one. A particular strength: the results remain consistent even on barrel roofs, because the Lok’n’Bak can be adjusted to suit the required radii. As a high-quality roofing tool and precision sheet metal working tool, it belongs in every professional roofing supply kit and sheet metal working supply kit – especially if you want to work productively and ergonomically.
