Product Description

1.5THLE Series Large Edge Adapter

A More Balanced Approach to Edge Detection

The 1.5THLE magnetic adapter locates a 1.5″ diameter SMR directly over an outside corner of two intersecting surfaces within ±0.0005″.  It also holds the centerpoint of the SMR precisely 1.000″ or 25mm (depending upon model selected) above the surface of the part being measured.  The SMR seats on a 3-point conical land.  This adapter is designed for proper balance to allow hands free use.
