The Tectus Hinge is a completely concealed steel hinge for interior and exterior doors. It’s totally invisible when the door is closed. But when the door is open, this hinge still looks good thanks to eight beautiful finish colors and a streamlined design. Give any space a seamless, luxury look with Tectus hinges. Available in five sizes and weight ratings, up to 660lbs per pair of hinges.
Price per unit. Adjust quantities after adding to cart.
Note:weight ratings listed are per pair of hinges. Matte Deep Black, Rustic Umber, and Satin Nickel Look finishes are in stock and ready to ship. Please contact us for lead times on other finishes.
Just because they’re invisible doesn’t mean they can’t also be sleek and elegant. Choose from eight premium finish colors to coordinate seamlessly with your space. All the Tectus hinge models have been tested for over a million cycles with no signs of wear. With weight capacities ranging from 88lbs to 660 lbs, you’re sure to find a hinge model that works for your door. But that’s not all—these hinges are compatible with wood, metal, and casing frames, making them phenomenally versatile. They can be adjusted in three dimensions to make installation easy. And the bearings require no oiling, so you don’t need to worry about maintaining them.
Where can you use concealed hinges? Anywhere you want a seamless, upscale look. Suitable for interior or exterior doors, these hinges offer an added layer of security. Because they aren't accessible when the door is closed, concealed hinges can prevent burglaries. For marine environments, we recommend the Stainless Steel Concealed Hinges.
