One compact jobsite tool
More than a stair gauge
DriveStop transforms the traditional framing-square stop into a multi-function tool built for fast layouts and everyday jobsite work.
02 / LAYOUT
Repeat with confidence
The large, flat face of the DriveStop body bears against the square for a stable reference during repeated stair, rafter and layout work.
03 / DRIVE
Built-in socket
Remove the locking bolt to expose the integrated 1/2-inch socket for lag bolts, circular-saw blade changes and other common tasks.
Protects at the locking point
Nylon non-marring bolt tip
The large, flat metal body rests against the square to provide a solid hold. At the locking point, the nylon-tipped bolt applies pressure without the bolt digging into or marring the square.
