National Mfg N342-550 Ss Heavy Duty Hinge Hasp 7.5 in 2-pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N342-550 is a 7.5-inch extra heavy duty hinge hasp constructed from stainless steel for long-term corrosion resistance. Designed for securing doors, gates, chests, and storage enclosures, this hasp is built for demanding applications where standard hardware falls short. The stainless steel staple provides added holding strength, and the square center hole is sized to accept a carriage bolt for a more tamper-resistant installation. At 2.25 pounds per package, the hardware is substantial and well-suited for trade and jobsite use.

This hinge hasp is appropriate for both residential and light commercial applications. It is rated for use with premium wood species including cedar and redwood, making it a fit for outdoor structures such as sheds, fencing, and deck enclosures where ACQ-treated lumber or naturally resistant woods are common. Its geometry supports around-the-corner mounting configurations, expanding its range of install scenarios. Each package includes 2 hasps.

Installation Notes

Installation is typically performed by a carpenter, general contractor, or knowledgeable DIYer using standard hand tools. For maximum security, fasten through the door or panel using carriage bolts through the square center hole rather than relying on wood screws alone. Ensure mounting surfaces are structurally sound before attaching. Follow any applicable local building codes for exterior hardware on security enclosures.
