Description:
These two translucent orange plastic triangles have rounded corners, triangle cutouts in their interiors, and slots for drawing lines parallel to each edge. They are both marked: SAFE-T TRIANGLE<sub>TM</sub> (/) PO BOX 692 LaGrange, IL 60525 (/) Shatter Resistant SAFE-T PLASTIC<sub>TM</sub> VIEW-THRU<sub>TM</sub>. The 4-7/8" 30°-60°-90° triangle is also marked: 42053. On the long leg, it has a scale of inches, divided to 1/16" for two inches and to 1/10" for two inches and numbered by ones from 1 to 4. The short leg has a centimeter scale divided to millimeters and numbered by ones from 0 to 6.
The 3-1/2" 45°-45°-90° triangle is also marked: 42054. One leg has a scale of inches, divided to 1/16" and numbered by ones from 1 to 3. The other leg has a centimeter scale divided to millimeters and numbered by ones from 0 to 8. The triangles were made in 1997 or earlier. In a company catalog (1998.0033.04), these models were renumbered to 42063 and 42064, respectively, and priced at 55¢ each. The pair could be purchased as a set for $1.35. The slots on the examples in the catalog were relocated to the corners of the triangles, so that they were easier to use for drawing templates of angles and triangles. Also, the model numbers were removed from the triangles. The form depicted in the 1998 catalog was still marketed in 2013.
