McKinney MPS679 4-1/2 x 4-1/2 MacPro Adjustable Spring Hinge Set | Standard Weight Self-Closing Hinge Kit
The McKinney MPS679 is a standard weight MacPro adjustable spring hinge set designed to provide reliable, self-closing performance for a single door opening. Supplied as a complete three-hinge kit, the MPS679 includes two MPS60 adjustable spring hinges and one MPB79 ball bearing butt hinge — everything needed to outfit one self-closing opening in a single package. The adjustable spring tension in the MPS60 hinges allows field adjustment of closing force without removing the hinges from the door, making this kit a practical, installer-friendly solution for commercial and institutional applications requiring consistent self-closing door operation. Each leaf is manufactured to a steel thickness of 0.134 in., reflecting the robust, standard weight construction characteristic of McKinney's MacPro hinge line. The MPS679 is sized at 4-1/2 in. x 4-1/2 in., a widely specified dimension suitable for standard commercial door and frame preparations.
