A sheet of diamond pattern material to make anything you want.
Diamond pattern on one side and smooth with no pattern on the other side.
Sheet measures 4" x 6" and is .0135" (1/64") thick.
It's thin enough that it can be bent around a form.
Great for truck beds, steps and guards. Use for rat rod interior door panels.
Here it is as a tool box and along the top of a pickup tailgate.
