National Hardware N129-155 T Hinge 6 in Steel Black 2-pack

Product Description

The NATIONAL HARDWARE N129-155 is a steel T hinge designed for gate, door, and utility panel applications where a durable strap-style hinge is required. The hinge features a 6-inch strap length and a 4-21/32-inch overall width, with a leaf thickness of 0.125 inches. It carries a load capacity of 48 pounds per hinge and is finished in black for a clean, consistent appearance on painted or dark-coated surfaces. With 8 mounting holes and 3 knuckles, the N129-155 provides solid fastening points and smooth pivot action. Each package contains 2 hinges. This hinge is installed by general contractors, carpenters, and maintenance tradespeople on residential and light commercial projects.

The N129-155 T hinge is suited for wooden gates, barn doors, shed doors, utility enclosures, and lightweight equipment panels. The handed design works for both left-hand and right-hand installations, making it a flexible stocking item for service trucks and supply rooms. The black powder finish blends with standard exterior hardware. A pad length of 4-1/4 inches provides ample surface area for secure attachment to door stiles and frame members.

Installation Notes

T hinges of this type are typically installed by carpenters, general contractors, or maintenance technicians using standard wood screws or bolts through the mounting holes. Power down any electrical components near the installation area and fully support the door or gate before mounting to prevent misalignment. Pre-drilling pilot holes in hardwood applications will prevent splitting and ensure the leaf seats flush against the surface. Follow applicable building codes for gate and door hardware where load requirements or access safety is a factor.
