Square 3-Pcs Hinge

Featuring a prismatic cross-section and a square form, this hinge is an innovative response to modern design language, achieving complete alignment with the profile lines of the frame and sash. The three-part structure, with a tri-sectional stress distribution and a reinforced axis, increases the load-bearing capacity up to 150–170 kg (per pair), preventing sash sagging during high-cycle operation. An exceptional choice for entrance doors, lobby doors, and luxury thermal-break windows.
