TECTUS TE 626 3D A8 Concealed Hinge

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!).
