Product Description

0.875THS Series Corner Adapter

For targeting an inside corner

The 0.875THS Series magnetic adapters provide an SMR nest which fits into any corner and puts a 0.875″ diameter SMR exactly 0.800″ away from the rising surface, within ±0.0005″. It also holds the centerpoint of the SMR 1.000″ ±0.0005″ (or 25mm for the metric version) above the base surface. A chamfer on the bottom side of this adapter provides a relief for any fillets or various strange things happening at the junction between the surfaces of the object being measured. The SMR seats on a 3-point conical land. Use the table below to find the item number for the desired target offset.
