TamBee Hidden Door Hinges Invisible Hinges Concealed Hinges Zinc Alloy 180 Degree Swing Hinge 3 Way Adjustable Butt Hinge 6 x 2.5 x 1 inch Black (2 PCs, Black)

These hinges were expensive, but they are very sturdy and are completely hidden. They are not easy to install, so you need an expert carpenter to do the job. We feel they are worth the money and the installation effort.

Turned out not to work for my project. they are very well made and function smoothly. I didn't consider the measurements for opening and my door was too thick. also the instructions are lacking a template to router with.

Both hinges cracked / broke shortly after we hung the door. Extremely poor quality! Hinges definately cannot support the rated weight rating of 88 lbs. Extremely disappointed they didn't even last a day

Muy buenas bisagras, se ven de excelente calidad y el acabado es sólido. Las usé para una puerta oculta y quedaron perfectas, no se ven nada y el movimiento es suave. Son un poco pesadas, pero eso demuestra que están bien hechas. La instalación requiere algo de precisión, pero el resultado vale la pena. Muy recomendadas si buscas un acabado limpio y moderno.Las recomiendo 100%

Great product and Good quality
