This is the ultimate hinge in the TECTUS universe. Not only does it have the 3-hour UL Rating, but it can also provides enhanced throw and can be used on doors with cladding up to 8mm (think mirrors or other laminates). A brute/beauty punch that is getting traction with architects who want to supersize their exterior doors, especially in coastal environments. And it comes with the usual indispensable TECTUS 3-D adjustability.
BUT, this hinge is expensive! If you don't require a 3-hour fire rating, consider the BaSys PIVOTA DXS-180 3D hinge with stainless steel knuckles or other alternatives from BaSys (one of the best German hinge manufactures now available in the US!).
The SIMONSWERK TECTUS TE 626 3D A8 concealed hinge is cast from solid non-magnetic stainless steel. UL listed for 3 hours with a high corrosion resistance, the TE 626 3D A8 is ideal for wood, steel or aluminum doors, and frames exposed to the elements.
The three-dimensional adjustability and maintenance-free slide bearing technology of the TE 626 3D A8 hinge system is for use with high-quality commercial doors.
