The Fretz M-104 Large Concave Stake 57mm Long is used to make gentle concave curves on narrow bracelets up to 1" (25mm). With sheet width of 1-1/2"(40mm) the curve will be quite dramatic. This shape works with 2" tubing and larger diameters with a maximum of 1-1/2" wide tubing or sheet.
Use with Fretz stake holder H-1 (112.600) or Fretz extended reach stake holder H-1L (112.719) for mounting onto a workbench or tabletop. If your work requires deeper access than the H-1L extended reach stake holder offers, you can get additional working room if you use this stake with the Fretz double ended stake holder T-101 (112.721) or the Fretz extender holder E-101 (112.726). Keep in mind that both the T-101 and the E-101 have larger tangs that will require larger stake holders.
