Granite Straight Edges 1.5x4x24, 1.5x5x36, 2x6x48 (USA Made)

Granite precision straight edges are available in 3 sizes. Select from 1.5x4x24 inches, 1.5x5x36 inches or 2x6x48 inches. Choose from Laboratory Grade or Inspection Grade, 1-Face or 2-Face.

Our high-quality black granite straight edges are MADE IN THE USA and provide the strongest, most durable and stable surfaces available. Black granite has a heavier density and is made of a finer grain that is less coarse than pink granite. Since granite accessories are often used for moving parts, pink granite tends to flake out in sections and can cause scratching. Black granite straight edges are more durable and help to avoid scratching.

Selecting a Grade:
When ordering, select Laboratory Grade AAor Inspection Grade A.

• Laboratory Grade AA is for high precision operations in temperature controlled environments.
• Inspection Grade A granite straight edges are best for general quality control use in final inspection rooms with a CMM.

Select 1-Face or 2-Face:

• 1-Face Accuracy on one long narrow edge.
• 2-Face Two long narrow edges flat and parallel to each other.
