Mark angles on any flat panel, from standing seam to 4 feet wide, for consistent cuts, speed, and accuracy. Every-time.

1. Loosen Clamp.
2. On overlap edge of all panels, mark position of
first row of fasteners.
3. Swing arm to desired pitch.
4. Lock clamp.
5. Place body over edge of panel. Align tool with
short or long point of angle measurement.
6. Extend arm as needed.
7. Scribe line.


As we contemplated additional needs in the contracting trade, we realized that a metal panel was sometimes challenging to mark without a helper and did not always get marked correctly. The Ridge–L, Ridge-SS, and the Ridge–9, series came to mind. These tools allow one person to mark a line on a full panel, up to a 12/12 pitch, and maintain the same angle from panel to panel. Only the long or short measurement is needed to line up the mark for the next panel.

Other methods are to use a board or long level to act as the straightedge, but two people are needed. You put marks at each edge and use a chalk line or a pencil to mark the panel. Many contractors have told us about being off on the line by “only a little bit,” and that ruined the sheet of metal they were using.

Crisp clean lines, and consistency is the secret to having an attractive building. “If you can build my neighbors to look that good, I want you to build one for me also” – Music to a contractors’ ears.

The Ridge-L is used on any square edge material from plywood, insulation board, or drywall.
