The Surface Applied Power Delivery is a device that allows power to jump from one side of a window/door jamb to the other when there is not enough room to drill or mortise into the door/window sash. This device only needs about 0.2 inches of gap inside the jamb, and can be applied with included adhesive or screw. When aligned correctly, power has two potential pass-through points in the contact, creating redundancy for enhanced longevity. 

Each purchase includes 2 sets of connectors, which is sufficient to power smart film/glass for a single window or door. 6" wire leads are included.
