KOLET Ball Bearing Door Hinges – 4x4 in, Square Leaves, 5/8 Radius, Brushed Nickel, 3-Pack

KOLET Ball Bearing Door Hinges — Durable, Quiet, and Ready for Everyday Use

For doors that see frequent traffic, you want hardware that lasts without drawing attention. KOLET ball bearing hinges are built from heavy-duty stainless steel and finished in brushed nickel for a clean, modern look. The standard 4x4 inch leaves pair with a 5/8 inch radius corner to fit most interior and exterior doors, while the included screws simplify upgrading in one session.

Designed for frequent use, these hinges deliver a smooth, quiet motion thanks to permanently lubricated bearings. Over time you may notice a steadier swing and less door noise, even in busy hallways or high-traffic rooms.

Key benefits

• Heavy-duty stainless steel construction resists rust and wear across seasons and climates.
• Brushed nickel finish provides lasting durability and a subtle, attractive appearance for visible doors.
• Ball bearing mechanism supports a heavy door with whisper-quiet operation, reducing nuisance noise in homes and offices.
• Non-removable pin design offers stable alignment with a low-maintenance profile.

What’s in the box

• Three hinges sized 4x4 inches for most doors.
• 27 screws included for quick mounting.
• Door leaf width around 1.73 inches (44 mm) and thickness about 0.1 inches (2.5 mm).

Compatibility and use

• Suitable for interior or exterior doors in homes, offices, and light commercial spaces.
