Easy to set up, this plumb bob and reel combination has a hang-hole in the case, an integral spring-loaded pin and a built-in magnet so it can be hung from a nail, pinned to a wooden stud, or stuck onto anything steel.
The bob is on a counterbalanced reel of braided line so it can be raised or lowered like a blind, stable at any point in its 3m (9' 10")
extension. The top of the 200g (7 oz) bob also has an integral swivel to minimize spinning.
A handy tool for the job site or home.
