McKinney T4A3786 Heavy Weight Hinge | 5" x 4-1/2" US32D Satin Stainless Steel
The McKinney T4A3786 is a heavy-duty, industrial-grade architectural hinge designed for high-traffic commercial environments. This heavy weight, stainless steel 5-knuckle hinge is engineered to support the immense physical stress of oversized or extra-heavy doors. With a robust .190 gauge thickness, it serves as a premier solution for door restoration in facilities where long-term durability is mandatory, such as hospitals, schools, and high-security public buildings.
Advanced Security & Performance
- Integrated Security NRP (Non-Removable Pin): This hinge features an NRP set screw hidden within the barrel that is inaccessible when the door is closed. This provides a vital solution for commercial door security, preventing unauthorized door removal on outward-swinging exterior doors.
- Corrosion-Resistant Stainless Steel: Constructed from high-grade stainless steel (ANSI A5111), this hinge provides a permanent solution for door edge reinforcement in environments prone to moisture or harsh weather.
- Oil-Impregnated Bearings: The TA Prefix denotes self-lubricating, non-ferrous bearings. These ensure a maintenance-free, silent operation while providing maximum resistance to clogging, corrosion, and premature hinge failure.
- Fire-Rated Approved: Unlike brass-based alternatives, the US32D Satin Stainless Steel construction is UL-listed and approved for use on fire-rated door assemblies (up to 3 hours).
