McKinney TA2372 4 1/2" US32D Standard Weight Hinge, 4 1/2 Inch Half Surface Hinge, Reversible, Ball Bearing, Non-Removable Pin, 630 Satin Stainless Steel

The McKinney TA2372 is a 4-1/2 inch standard weight half surface hinge built for reliable performance on medium-frequency commercial openings. Constructed with a five knuckle, ball bearing design, it delivers smooth, consistent door movement while supporting the weight of the door over years of use. Its reversible configuration allows installation on either hand of door, and the non-removable pin (NRP) adds security by preventing removal from the hinge side. Finished in 630 satin stainless steel (US32D), this hinge offers excellent corrosion resistance and a clean, professional appearance suited to a wide range of interior and exterior applications.

Features

• Standard weight construction ideal for medium-frequency door openings.
• Five knuckle ball bearing design ensures smooth, quiet operation and long service life.
• Half surface mounting fits applications where the frame leaf is mortised and the door leaf surface-applied.
• Reversible design allows use on either handing of the door.
• Non-removable pin (NRP) improves security on exterior and out-swinging doors.
• Durable 630 satin stainless steel finish resists corrosion and wear.

Functional Details

The TA2372 uses a ball bearing system between the knuckles to reduce friction, allowing the door to swing effortlessly while distributing load evenly. The half surface configuration mortises into the frame while mounting to the surface of the door, making it a practical solution for specific installation conditions.
