A closer look

Tempered steel at 16 by 24 inches. Heavier body than aluminum, takes drops without flexing.

Permanently impressed gradations on the acid-washed blade. Scales stay legible past stamped markings on cheaper squares.

Standard 16 × 24 framing-square layout, in the steel body that holds up to job-site abuse.
