Expand then contract for your instant visual guideSetting out a row of screws, pins or dowels quickly and without too much hassle isn't easy. Usual process: Measure the length of the run and divide by the number of points plus one. Then divide the extra one point by two and that gives your starting and finishing points. Then measure out each of the remaining points by the total on the calculator. Alternatively extend a Point-2-Point™ fully and bring the mechanism down to the required size. Lock the setting in place with the Point-2-Point's™ pinch bolts and you're ready to start marking out.
