STRAIGHT EDGES
NO. 9169 SERIES
Taft-Peirce Steel Straight Edges provide an extremely accurate reference surface for scribing straight lines and for checking surface straightness and flatness. All sizes are proportioned for proper balance between rigidity and weight. Sizes 36" and longer have marked support points which should be used to minimize deflection due to gravity. Properly supported and cared for, these straight edges will retain their accuracy almost indefinitely. When not in use, they should be hung vertically by the hole provided in one end. Steel Straight Edges may be readily self-checked by inverting them on proper support points and indicating both sides at the center.
