McKinney TB2714 4-1/2 x 4-1/2 Two Ball Bearing Standard Weight Full Mortise Hinge
The McKinney TB2714 is a full mortise, five-knuckle, standard weight butt hinge featuring two ball bearings for smooth, low-friction operation. Measuring 4-1/2 inches by 4-1/2 inches, this hinge is engineered for commercial and institutional door applications where reliable, long-term performance is essential. The TB2714 is part of McKinney's trusted line of architectural door hardware, a brand with a long heritage in premium hinge manufacturing.
Full mortise hinges are designed so that both leaves recess fully into the door edge and door frame, producing a clean, flush installation. The five-knuckle barrel configuration provides added strength and stability along the full height of the hinge, distributing door weight evenly across the pin. The two ball bearing design reduces operational friction and wear, making the TB2714 well-suited to doors that see frequent use.
Institutional Grade Features & Benefits
- Full Mortise Installation: Both leaves recess into the door and frame for a clean, professional flush fit — the industry-standard configuration for commercial doors.
- Two Ball Bearings: Precision ball bearings between knuckles reduce pivot friction, supporting smooth, consistent door swing over the life of the hinge.
- Five-Knuckle Barrel: The five-knuckle design distributes load across a longer barrel, improving stability and reducing stress on the pin and leaves.
- Standard Weight Construction: At 0.134 in. steel leaf thickness, the TB2714 meets the dimensional standard for standard weight hinges — balancing robust durability with appropriate weight for the door size.
- 4-1/2 x 4-1/2 In. Leaf Dimensions: A widely specified commercial hinge size, compatible with standard commercial door and frame preparations across many project types.
- McKinney Brand Quality: McKinney hinges are a long-established, architect-specified product line trusted across commercial, institutional, and industrial construction.
