This Hidden Door Hinge and Opening Positioning Template Kit is a precision tool designed for installing 6-inch or 7-inch concealed hinges with ease. It eliminates the need for multiple jigs, allowing you to route hinge mortises accurately for invisible doors, folding doors, or feature walls. The included hinges are three-dimensionally adjustable (vertical ±2.5mm, horizontal ±2.5mm, depth ±1.0mm), making alignment simple without removing the door. Please note: this template is not for heavy repeated use; it works best with Lipshome invisible door hinges—confirm compatibility before purchase. Ideal for achieving a sleek, sophisticated, seamless door installation.
