Review on Draper Expert Brass Plumb Approx by Michael Eldridge

This is a product. I like the one-piece construction and the cylindrical shape that makes it easy to store. It's not overly heavy but has enough bulk to get the job done. I like that it can be attached to a hole that runs horizontally. However, one feature that is not clear from the product description is that there are two holes at the top that allow you to connect either a horizontal hole or a second vertical hole at the top.
