McKinney MPS60 4-1/2 x 4-1/2 MacPro Adjustable Spring Hinge — Full Mortise Self-Closing

The McKinney MPS60 is a full mortise, concealed-bearing, adjustable spring hinge engineered to deliver consistent self-closing performance on standard commercial and institutional doors. Part of McKinney's MacPro standard-weight steel hinge line, the MPS60 measures 4-1/2 inches by 4-1/2 inches and is constructed from 0.134-inch steel leaf stock — the precise gauge specified in the McKinney full-line catalog. The integrated spring mechanism is field-adjustable, allowing installers to dial in closing tension to suit door weight and frequency of use without removing the hinge from the door.

Institutional-Grade Features & Benefits

• Full Mortise Installation: Both hinge leaves are mortised flush into the door edge and frame, providing a clean, professional appearance and a secure mechanical connection that resists racking under high-cycle use.
• Concealed Bearing Construction: Internal bearings reduce pivot friction, promoting smooth, controlled door travel throughout the closing arc and extending the service life of the hinge under repeated daily use.
• Adjustable Spring Tension: The spring mechanism can be tuned in the field to increase or decrease closing force, giving facility managers and installers precise control without replacing hardware.
• Self-Closing Function: The built-in spring automatically returns the door to the closed position after each use — an essential feature wherever positive latching or controlled access is required.
• MacPro Standard-Weight Steel: McKinney's MacPro designation indicates a standard-weight steel construction suited to commercial-grade door applications demanding durability and dimensional consistency.
• 0.134-Inch Steel Leaf Thickness: The exact leaf gauge per the McKinney full-line catalog ensures compatibility with standard full-mortise prep specifications and reliable structural performance.
• 4-1/2 x 4-1/2 Inch Leaf Size: A widely accepted commercial hinge dimension compatible with standard door prep and commonly paired with hollow metal, wood, and aluminum door systems.
