Aluminum 96,8 cm straight edge

Precisely designed and manufactured straight edge with dimentions of 960x46x11mm. Its head is cut at 90^o angle and grinded. 

The straight edge has measuring tapes on both sides (one goes from left to right, the other goes from right to left). It's made from red anodyzed aluminum. Slight groove going throughout the whole lenght of the ruler makes holding and moving it much easier.

It's a perfect tool for checking flat surfaces as well as marking straight lines.
