Swanson Framing Wizard

Folding aluminum framing square that combines 5 tools in one (framing square, try square, miter square, angle finder, saw guide), with the same "One-Number Method" rafter layout system as Swanson's Speed Square, extended to 12"/16"/24" on-center layout. Adjustable set screw lets you re-true it to 90° if it ever goes out of square.

Swanson is the established name-brand reference for speed/framing squares — the real thing, not a knockoff. Relevant to the property build's framing work specifically.
