Rapid Rafter Original — polymer double-sided square

Built on the framing wall

Designed by a carpenter, not a boardroom.

Peter Toomey has framed in Liberty Hill, Texas since 1984. He invented the Rapid Rafter to fix a problem he hit every day — and it became the first real change to the rafter square in nearly a century. Made in the USA. Patented. Built to outlast the truck you carry it in.

The difference

One pass. Both faces and the top edge.

A traditional square marks one face — then you flip the square or the board and mark again. The Rapid Rafter straddles the stock and marks three sides in a single motion, with a perfect perpendicular line even on rough boards or boards with wane.

  • Three sides, one motion. Both faces and the top edge — ideal for layout marking.
  • Perfect line, any board. Registers true on rough, twisted, or wane-edged stock.
  • Folds flat. Works exactly like the everyday square in your apron.
