There is simply no quicker or easier way to scribe treads and risers than with our Stair Jig. Adjusts easily without tools from 32" to 52" for a perfect fit every time. For lengths 52" to 72", just add an Extender. Keep adding 20" Extenders to span any length tread. All joints lock tightly for dead-solid accuracy. The T-bar angle adjusts to greater than 45 degrees. And you'll appreciate its lightweight, all-metal construction.
