4" X 4" Ball Bearing Hinge Square Corner With 5/8" Radius Corner Polished Brass Finish - Sold As Pairs

A Ball-Bearing Hinge is equipped with precision ball bearings between the knuckles to significantly reduce friction during operation. This design provides smoother door movement, eliminates squeaking, reduces metal-to-metal wear, and extends hinge lifespan under repeated daily use.

If you are experiencing squeaking doors, binding, or premature hinge wear, our 4 x 4 ball bearing hinges are engineered to correct those issues immediately.

Designed for contractors, installers, and commercial applications, this hinge delivers reliable long-term performance in both residential and light commercial environments.

Our hinges are compatible with most major hinge brands, including Penrod.

Why Choose a Ball Bearing Hinge?

Ball bearing hinges are preferred in higher-traffic applications because they:

• Deliver smoother door swing

• Eliminate squeaking over time

• Reduce friction between hinge knuckles

• Increase durability under load

• Perform better on heavier solid-core doors

For 1 5/8" to 1 3/4" thick doors, a 4" x 4" hinge is the industry standard for proper weight distribution and alignment.

Finish & Material Details

This hinge features:

• Solid steel construction for structural strength

• Bright polished brass finish for a clean, traditional appearance

• Lacquer-coated surface to help resist tarnishing
