About this product
The WUKO 1004837 Standing Seam Opener is a hand tool roofers and sheet metal mechanics use to open a seam or hem that has already been closed. It is the tool you reach for when a panel has to come out for a repair, when a new section ties into an existing standing seam roof, or when a seam was closed in the wrong place and needs to be reworked.
WUKO lists it under item number 1004837 and makes it in Austria. Opening a seam by hand with the right pliers lets you back the metal off gradually, rather than prying with a screwdriver and kinking or scratching the panel, so the seam can be closed again cleanly.
It belongs in the same bag as the rest of the WUKO hand tools in this catalog. After a repair, close single-lock seams with the WUKO Lock’n’Roller or the WUKO Large Straight Seaming Pliers, and use the WUKO Flat Nose Pliers or Round Nose Pliers for small folds and end details. For double-lock seams, the WUKO Double Welt Iron gives you a solid anvil to work against, and the ESE Finish Hand Seamer 180 Degree completes the second fold.
It is a handy addition for service crews who maintain copper, zinc and painted aluminum roofs.
