McKinney MPS60 4-1/2 x 4-1/2 MacPro Adjustable Spring Hinge — Standard Weight Single Acting
The McKinney MPS60 is a 4-1/2 in. x 4-1/2 in. MacPro adjustable spring hinge engineered for standard weight, single-acting door applications where reliable, field-adjustable self-closing performance is required. Also referenced by the part number MPS60, this hinge integrates a built-in spring mechanism whose tension can be adjusted directly in the field — no specialized tools or door removal required — allowing installers and facility maintenance teams to dial in the precise closing force to suit the door weight and opening conditions. As a single-acting spring hinge, the door self-closes in one direction while swinging freely in the other, making the MPS60 a practical choice wherever consistent, automatic door closure is needed without a separate overhead door closer.
