National Marker N342527 Extra Heavy Tee Hinge 8 in

Product Description

The NATIONAL MARKER N342527 is an 8-inch extra heavy T hinge constructed from stainless steel for long-term rust resistance in demanding exterior applications. The hinge features a patented bearing design that eliminates metal-to-metal contact, producing smooth, quiet operation over extended service life. Offset screw holes increase pull-out resistance at the mounting points. The tight pin design supports both right-hand and left-hand applications without requiring separate hardware. This hinge meets ANSI/BHMA A156.20 bearing grade cycle requirements, rated for 100,000 cycles. It is sold individually and is suited for installation by carpenters, contractors, and general tradespeople working on gates, doors, and heavy-duty exterior assemblies.

The N342527 is rated ACQ safe, making it compatible with pressure-treated lumber as well as premium woods such as cedar and redwood. This makes it appropriate for residential and light commercial gate construction, barn doors, deck access panels, and exterior utility enclosures where moisture exposure and treated-wood chemistry would corrode standard steel hardware. The stainless steel construction is well suited for coastal environments, high-humidity settings, and any installation where long-term corrosion resistance is a priority.

Key Features

• Stainless steel construction provides rust resistance for exterior and high-moisture environments
• ACQ safe — compatible with pressure-treated lumber, cedar, and redwood
• Patented bearing design eliminates metal-to-metal contact for smooth, quiet operation
• Offset screw holes deliver added pull-out strength at mounting points
• Tight pin accommodates right-hand or left-hand installation without separate components
• Meets ANSI/BHMA A156.20 bearing grade cycle requirements at 100,000 cycles

Compatibility

Designed as an OEM-style replacement or new-installation T hinge for exterior gates, heavy-duty doors, and utility enclosures requiring an 8-inch stainless steel hinge. Also referenced under National catalog model No. V285.

Installation Notes

Installation is within the scope of general carpentry and finish trades. Power down or de-energize any electrically controlled gate or door system before beginning work. Use appropriately sized stainless steel screws to maintain corrosion resistance throughout the assembly — mixing fastener metals can accelerate galvanic corrosion in wet environments. Confirm that the mounting substrate provides adequate thickness and density to support the offset screw hole pattern under load.
