Elbow building aluminum MT2062 is required to mark and identify angles. Bilateral shoulder tool with striping on both sides makes it as easy and sure to make a mark even in the most remote places. Aluminum alloy as a manufacturing material makes the assembling angle MT2062 resistant to corrosion, moisture and other environmental conditions. Additional stiffeners maintain the evenness of the measurement surface. Shoulder is fixed in block two rivets and additional screw that prevents it from loosening and ensures maximum tool life.
