McBowery Heavy Duty Concealed Hidden Door Hinges make a door disappear into the wall. Each concealed door hinge mortises into the edge of the door and the frame, so nothing is visible when the door is closed. That makes them the invisible door hinge of choice for hidden doors, secret doors, secret rooms, bookcase doors, murphy style doors and flush wall doors. Unlike most hidden door hinges, every purchase comes with a matched router bit and a rigid, reusable routing template (not a paper template), so you can cut clean, exact pockets with your router. One pair of these heavy duty hidden door hinges holds doors up to 132 lb. (60 kg). Each hinge is 3-way adjustable: ±2.5 mm up and down, ±2 mm side to side and ±1 mm in and out. Dial in perfectly even gaps and a flush fit with the included Allen key, without taking the door off. The 180° swing lets the door open fully. In the box: 2 concealed door hinges, 8 cover plates, 8 screws, 2 Allen keys, plus 1 router bit and 1 rigid routing template with every purchase. Available in Matte Black, Satin Chrome and Champagne Gold.
