All BUSCH PRECISION straight edges feature the strong I-beam design with precision ground or hand scraped finishes in accuracies within the tolerances indicated below. You can select the most appropriate tool for your leveling or alignment application.

In addition to the wide selection of sizes, please note the important quality features offered:

Strong I-beam design, cored and ribbed for rigidity and lightness
Quality, close-grained castings, specially treated for stability
Precision accuracies in tenths of thousandths
Precision ground surface finishes of 16 RMS or better
Hand scraped finishes also available

In applications requiring longer length straight edges where convenience in handling is a concern.
For storage and transport, specially fitted cases are available at additional cost for all straight edges.

RMS

A roughness height rating. It is the abbreviation for root mean square and is a measure of surface roughness in terms of the arithmetic average of the squares of the variances in a given surface. (Fed. Spec. Mil. Std. 10A)

Straight Edge Accuracy

The overall accuracy of each straight edge is carefully inspected and calibrated to insure it falls within the tolerance specified. In use, straightness is dependent upon proper support points for straight edges 60" and longer. Use of these support points minimizes the deflection due to gravity.

60"	6 - 12"
72"	13 - 20"
96"	20 - 26"
120"	25 - 30"
144"	28 - 35"
168"	34 - 40"

To check the accuracy of a properly supported parallel straight edge, indicate one edge or face in the center; then turn the straight edge over and indicate the opposite edge or face in the same manner. Any gravitational deflection should be identical. By measuring the degree of deflection, proper compensation can be made in any alignment application.

To maintain precision tolerances, straight edges must be handled carefully to avoid shock damage. In storage, they should be stored with full horizontal support. Where possible, they should be hung vertically with proper safeguards.
