The Steel Dog® StringFinger quickly clips over 1-1/8” form panels at the corners to hold your line-up string exactly even with the inside edges of the forms in both directions--effortlessly.

The StringFinger’s ingenious, spring-steel design allows it to slip down over the panels on a 90 deg outside corner and hold its position without nails.



  •  Accurate alignment of string with inside form faces

  •  No nailing required

  •  Works with 1x1 steel corners or 90 deg corner clips

  •  Lightweight and inexpensive
