ALUMINUM
PARALLEL STRAIGHT EDGES | MASTER SQUARE

A6100/6200 Series - ALUMINUM PARALLEL STRAIGHT EDGES

Aluminum Straight Edges are made in the same sizes as most cost iron straight edges.

Starting with a cast aluminum alloy body, this series is specially treated for stress-relief and stability.

After premachining, the top and bottom faces are fitted with cast iron wear plates which are then bonded to the aluminum body with superstrong space-age adhesive.

At less than half the weight of cast iron, these aluminum straight edges combine light weight convenience with the wear qualities of cast iron.

Available in 10 sizes with precision ground or hand scraped finishes with faces parallel and straight within the tolerances indicated.
