Standard & Butterfly Hinge

Standard & Butterfly Hinges are universal lightweight door and window opening and closing hardware accessories, widely compatible with residential wooden doors, decorative doors, light cabinet doors, and ordinary interior doors. Standard hinges feature a symmetrical, straight-blade structure; butterfly hinges, shaped like butterfly wings, require no grooves and offer a wide opening angle. The core advantages of both types of hinges are wide compatibility, easy installation, quiet and smooth operation, and high cost-effectiveness. They effectively prevent door misalignment, looseness, and abnormal noises during opening and closing, making them suitable for both residential and commercial applications. Standard hinge specifications, 1.0–3.0mm hinge thickness, and solid, integrated pins support a 180° wide-angle opening and closing. The overall structure is compact, meeting the standard usage requirements for various light-duty doors. The ball bearing version is suitable for heavy-duty doors and can be customized according to door weight and opening frequency, meeting the needs of all scenarios from lightweight residential doors to heavy-duty industrial doors.
