Busch Aluminum Parallel Straight Edge 2"W x 72"L x 4" H - A6106

• BUSCH PRECISION Aluminum Straight Edges are made to the same tolerances as Cast Iron Straight Edges (in five additional sizes).
• Starting with a cast aluminum alloy body, this series is specially treated for stress-relief and stability.
• After pre-machining, the top and bottom faces are fitted with cast iron wear plates which are then bonded to the aluminum body with super strong 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.
