Description

Purpose‑built for safer, smoother door operation, this architectural hinge features an extended pin/knuckle geometry that helps minimize pinch risk along the hinge‑side gap as the door closes. Stainless‑steel leaves (SS304/201) deliver strength and corrosion resistance, while two ball bearings (2BB) provide a consistent, quiet swing for standard‑duty openings. The five‑knuckle construction and a robust 3.4 mm leaf thickness offer long service life. A template screw pattern enables fast, repeatable installation across timber or metal frames. Available in 4.5″ × 4.0″ and 4.5″ × 4.5″ sizes, with finish options to match broader hardware suites.
