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
