McKinney T4A3386-5x4-1/2-NRP Full Mortise Heavy Weight Five Knuckle Hinge, Non-Removable Pin

The McKinney T4A3386 is a full mortise, heavy weight five knuckle hinge built for demanding commercial openings where high-frequency traffic and heavier doors are the norm. Measuring 5 inches by 4-1/2 inches, this hinge features concealed ball bearings that deliver smooth, quiet operation over the life of the door. The non-removable pin (NRP) design adds a critical layer of security, preventing the pin from being tapped out when the door is closed—making it a smart choice for exterior and out-swinging doors. Manufactured to McKinney's exacting standards, the T4A3386 offers dependable performance and long service life on institutional, healthcare, and other heavy-use applications.

Functional Details

The non-removable pin feature secures the hinge pin in place so it cannot be removed while the door is in the closed position, protecting against forced entry on out-swing doors. The concealed ball bearings carry the door weight and reduce wear during repeated use.
