KOLET Ball Bearing Door Hinges – 4x4 In, Matte Black Stainless Steel, 3 Pack

Durable design for everyday doors

KOLET Ball Bearing Door Hinges combine heavy‑duty stainless steel with a matte black finish to resist wear and corrosion. Built for real life, they promise long service life, with testing showing over a decade of reliable use and 50,000+ cycles. The result is a sturdy, confident feel at every door swing.

Beyond looks, these hinges are engineered to withstand frequent use and heavier doors, delivering a balanced blend of strength and elegance for interior and exterior applications alike.

Quiet, smooth operation

The hinge features permanently lubricated bearings that promote whisper‑quiet opening and closing. The ball bearing design reduces friction, helping doors glide smoothly even in high‑traffic areas. This means less interruption and a calmer entry and exit in busy spaces.

What’s included and how to install

Each package includes 3 hinges and 27 screws, making upgrade or installation straightforward. Before you install, note the typical dimensions: door leaf width is 1.73 inches (44 mm) and thickness is 0.1 inch (2.5 mm). The left/right opening capability and the standard 4x4 inch leaf size fit most doors.

• Standard 4x4 inch leafs suit most doors and gates.
• Non‑removable pin due to the ball bearing structure helps maintain alignment over time.

Versatile for many doors and settings

Crafted from top‑tier stainless steel with a matte coating, these hinges work well for interior or exterior doors in residential or commercial environments. A 3‑hinge setup can provide solid support for doors up to roughly 110 pounds (50 kg), offering dependable stability for daily use.

• Suitable for left or right opening doors.
• Rust‑resistant finish helps maintain appearance in varied climates.

Tips for best results

For optimal performance, avoid forced movement and don’t attempt to remove the pin from the ball bearing design. Regular cleaning and proper alignment after installation help keep hinges functioning quietly and smoothly over time.
