Features: Fits all sizes of flange: 1/8”- 1/4”, 5/16”- 1/2” and 9/16”- 3/4”.  Made in the USA.  FAST – Hammer on beam clamps the first time – every time. Install bang-on minnies in seconds to finish jobs in half the time. Just load a clip, line it up, and hammer away.  MAGNETIC – Clip Whacker holds your hammer-on beam clamps in place using a rare earth magnet. This strong magnet keeps a tight hold on your clips so you can work faster.  SAFE – You don’t have to worry about hitting your thumb anymore. Enjoy a bigger target for your hammer and reduce the risk of injured hands. The hammering surface is rounded and wider than the tool to protect your hands.  PORTABLE – The Clip Whacker is small enough to fit in any tool pouch or bag and the aircraft-grade aluminum makes it lightweight and easy to maneuver.
