387-24 Starrett Steel Straight Edge, 24*(600mm) with Beveled and graduated edge

387-24
Starrett Steel Straight Edge
with beveled edge and graduations

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 380 Series are not beveled or graduated. The 385 Series are
beveled one edge, but not graduated. The 387 Series has one edge that
is both beveled and graduated in 32nds of an inch.

The 380 and 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.
