Title: Pointless and useless
Review: This gadget is available in both plastic and metal. The one Amazon ships is plastic. For about 3 bucks it would be an OK novelty. Here is why it's useless. The only thing it does is to hook the end of your tape with a 3/16" offset to account for the reveal, when you measure the inside dimension. You still have to add 3/16" to the measurement for the reveal at the other end. If you can add 3/16, you are certainly capable of adding 3/8". And you don't need any tool for that, just measure the inside of the jamb. The other "feature", the reveal guide, is already in every carpenter's tool box. It's called a step or trim gage, and it's adjustable for ANY reveal. The Bench Dog is for 3/16" reveal only.
