Large T-square protractor for use in construction
A framing T-square protractor apparatus includes a first rule element having first and second edges, a surface, and a length of about 3 ft between the first and second edges; a second rule element having first and second edges, a surface, and a length of about 5 ft between the first and second edges, the second rule element being pivotally connected to the first rule element midway between the first and second edges of the first rule element; and a semi-circular element extending between the first and second edges of the first rule element to form an 180 degrees arc with 0 to 90 degrees angle indicia on each half, the semi-circular element being connected to the first and second edges of the first rule element and being adapted to movably receive the second rule element for sliding along the semi-circular element.
