Plumb Bobs are one of the simplest tools to establish a perfect vertical line or plumb line. Our set comes with 2 precision made All Brass Plumb Bobs (16 oz and 8 oz). Each plumb bob comes with 2 replaceable steel tips (one is hidden in cap), for a total of 4 steel tips. Both sizes use the same interchangeable caps and tips, making switching sizes quick and easy. Our Retractable Line Reel comes with approximately 14 feet of bright orange braided nylon cord, rare earth magnets to attach the reel to steel or iron and a fold out bracket to hang the reel on a nail, screw or tack. To attach the cord to the plumb bob, just remove the screw in cap; thread the cord through the center opening; knot it and reattach cap to plumb bob. The nylon cord pulls easily out of the reel. Press the locking lever once to hold the cord in place. Press the locking lever again to release the cord. When done the line will self retract into the reel. As a bonus, our kit includes a Specialty Pencil Sharpener designed for cutting carpenters pencils and 2 pencils to get you started. All this packaged in an attractive, durable, zippered protective case.
