The Vampire™ T-Bar Tool
The Vampire™ T-Bar Tool is specifically designed to assist in installing Vampire Hangers.
With the jaws set on the third largest opening, the Vampire™ T-Bar Tool's top jaw will go into the hole of the hanger. The bottom jaw will grasp the back of the gutter with the bar between the hanger's prongs and the top of the gutter.
A simple squeeze of the Vampire™ T-Bar Tool will allow the hanger's prongs to pierce the back of the gutter.
Then, using the tool as pliers, with the lower jaw under the prongs, bend the prongs up for a firm and permanent fit.
With practice, the hangers will be installed as quickly as your machine will roll out the gutter.
