Kolet Ball Bearing Door Hinges – 4x4 in, Matte Black, 3-Pack

Elevate door performance with Kolet ball bearing hinges

Designed for daily use, these hinges feature permanently lubricated bearings that minimize friction. The result is smooth, quiet operation as doors swing open and closed, even under heavy use. Expect a more consistent swing and less noise over time without relying on frequent maintenance.

Built to endure, the hinges use heavy-duty stainless steel finished in matte black. This combination resists rust and wear, helping doors stay aligned and looking sharp for years. The design supports long service life and frequent cycling, making them a practical choice for busy entryways, gates, and interior doors alike.

What you get and how it fits

• Size and packaging: standard leaves measure 4 x 4 inches; each pack includes 3 hinges and 27 screws for installation.
• Before you install, measure the door leaf width to ensure a clean fit. The door leaf is about 1.73 inches wide (44 mm) and 0.1 inch thick (2.5 mm).
• Every hinge is carefully wrapped to prevent scratches during shipping and handling.

Versatility for various settings

• Suitable for interior and exterior use, residential and commercial applications, and both left and right opening doors.
• The three hinges provide solid support for door weight up to 110 lbs (50 kg), offering reliable performance for medium to heavy doors or gates.

Important design details

• Note: The pin is non-removable due to the ball bearing structure, a choice that supports durability and stable alignment over time.

In everyday spaces—hallways, laundry rooms, storage closets, or exterior entrances—these Kolet hinges can contribute to a smoother door experience. The matte black finish blends with modern hardware, while the steel construction stands up to daily wear.
