McKinney MKCL2500 5x4-1/2 Heavy Weight Cam-Lift Stainless Steel Hinge | Full Mortise
The McKinney MKCL2500 is a full mortise, heavy weight cam-lift hinge engineered for demanding door applications where reliable, gravity-assisted self-closing and threshold clearance are required. Also referenced as the McKinney CL2500 cam-lift hinge, this 5-inch by 4-1/2-inch stainless steel hinge features a precision-cammed knuckle that raises the door as it swings open, allowing the door leaf to clear carpet, thresholds, and raised floor transitions without obstruction. Once released, the cam geometry allows gravity to draw the door back toward the closed position — no closer required for that self-closing action. Built to full mortise installation standards, the MKCL2500 installs flush into routed recesses on both the door edge and the door frame, providing a clean, professional finish consistent with architectural-grade hardware specifications.
Institutional Grade Features & Benefits
- Cam-Lift Mechanism: A cammed knuckle raises the door as it opens, providing automatic clearance over carpet, thresholds, and raised sill conditions — eliminating the need for door undercut adjustments in many situations.
- Gravity Self-Closing Action: The cam geometry causes the door to self-close under gravity once released, reducing reliance on additional closing hardware for basic return-to-close performance.
- Full Mortise Installation: Installs flush into mortised recesses on both the door stile and frame jamb, delivering a clean architectural profile and maximum bearing surface contact for heavy door applications.
- Heavy Weight Construction: Designed for heavy-duty door installations where standard-weight hinges would be insufficient; the substantial 0.190-inch steel leaf thickness provides enhanced durability and load-bearing capacity.
- Stainless Steel Construction: Corrosion-resistant stainless steel material is well suited for high-traffic, high-humidity, or hygiene-sensitive environments where long service life is a priority.
- 5 x 4-1/2 Inch Hinge Size: The 5-inch height by 4-1/2-inch open width dimension is appropriate for wide, heavy commercial door panels that require expanded bearing area and stability.
- McKinney Quality: McKinney is a recognized name in commercial architectural hinges, and the MKCL2500 is manufactured to the dimensional and material standards expected in professional door hardware specifications.
