#0014, 12 inch Rule: To successfully build any craftsman Kit you'll need an accurate rule. Unlike our 6-inch rule which is great for carrying in your pocket, this 12-inch rule will be your go-to ruler during the assembly of your Campbell kit. We use this 12-inch rule exclusively during the wood-cutting and packing processes at our manufacturing facility in Oregon. It is made of stainless steel and has the common dimensional divisions of 1/8", 1/16", 1/32" and 1/64". This is will be one of your most-used tools on your assembly table.
