| This tool will soon become your valued assistant. Secure the plumb partner to nearly any surface using one of three methods . . . a retractable metal hook, built-in pin, or the strong magnet. Holds plumb bob about two inches away from a wall, but by means of a small hook at the front of the tool the string can "hug" the wall. Works with any plumb bob 100 grams to 850 grams in weight. |
