Telescopic Gauge Set
The No. 579 Series is similar to the No. 229 Series except that it has a slightly greater
range, and the handles are rigidly attached to the contact plungers and are automatically self-centering. Also, the No. 579 gages have two telescoping contacts.
Constant spring tension gives uniform contact pressure and both plungers are easily locked at any desired setting.
