The Vampire™ T-Bar is precision stamped from .063″ aluminum. The assembly of the Vampire™ T-Bar Hanger includes a custom, strong rivet securing the strap to the hanger. The Vampire™ T-Bar is compatible with all types of seamless gutters. The installation process joins this pre-fabricated hanger to the gutter in a unique manner, which assures the strength of the final installation. The two prongs on the hanger (The Vampire™ Fangs) pierce through the back of the gutter and are bent up for permanent attachment to the gutter. The Vampire Tool is sold separately and is required for installation. The Vampire hanger is available for both 5” and 6” gutter.
