Double-Action Spring Hinge 150 mm Patina for Interior Swing Doors Up to 34 kg

Product Overview

The Zawias sprężynowy wahadłowy 150 mm patyna is a double-action spring hinge designed for interior, non-rebated doors up to 34 kg in weight and 75 cm in width when using two hinges. Commonly used in residential and light commercial settings, it enables doors to swing in both directions and return to the closed position automatically. Installation requires a clearance of approximately 5 mm between the door leaf and frame, and at least 10 mm from the door to the floor or threshold.

The key differentiator for this hinge is its double-action mechanism, which simplifies accessibility and traffic flow in areas requiring doors to open both ways, such as kitchens, offices, and customer areas. This feature minimizes the need for additional door hardware or complex installation, reducing procurement and labor costs for contractors and facility managers seeking efficient solutions for interior swing doors. Particularly suited for refurbishment projects and bulk procurement for hospitality or retail fit-outs.
