Manufacturer: STAKF Brand: Starrett Model: 385-24

These straight edges are precision ground and nicely finished to rigid Starrett standards. They are unexcelled for drawing or scribing straight lines and checking surfaces for straightness. Their thickness and design permit them to retain shape and accuracy, but still be portable and easy to handle. The No. 385 Series are beveled one edge, but not graduated. The No. 385 Series in sizes 36" and longer are marked with arrows at two suspension points. If the straight edges are brought to the work and used on edge, they should be suspended at these two points to minimize deflection. Most jobs involve the use of straight edges in the flat position - and it is in this position that we check most stringently.
