National Hardware N148-304 Piano Hinge 48 in Steel Brass

Product Description

The NATIONAL HARDWARE N148-304 is a full-surface piano hinge designed for continuous load distribution along the full length of a door, lid, or panel. Constructed from steel with a brass finish, this hinge measures 48 inches in overall length and 1.5 inches in overall width, with a leaf thickness of 0.042 inches. The steel pin provides consistent pivot action under repeated use. This hinge is well suited for cabinet doors, storage chest lids, toolbox panels, and similar applications where a standard butt hinge would not provide adequate support. Installation is handled by finish carpenters, cabinetmakers, and general contractors.

This piano hinge is appropriate for residential and light commercial millwork applications. Common use cases include piano fallboards, toy box lids, workbench covers, and fold-down panels in furniture or cabinetry. Its full-surface mount design allows attachment directly to the face of both mating surfaces without requiring a routed mortise, simplifying installation on flat stock material.

Key Features

• Full-surface mount eliminates the need for mortising
• 48-inch continuous length distributes load evenly across the joint
• Steel construction with brass finish for corrosion resistance and appearance
• Steel pin for durable pivot performance
• 1.5-inch overall width suits standard cabinetry and panel applications
• 0.042-inch leaf thickness provides a low-profile fit at the joint

Compatibility

Designed as an OEM-style replacement or new-installation continuous hinge for cabinet doors, chest lids, fold-down panels, and similar full-surface hinge applications in residential and light commercial millwork.

Installation Notes

This hinge is typically installed by carpenters, cabinetmakers, or skilled tradespeople using standard woodworking hand tools and fasteners appropriate to the substrate material. Align the hinge leaf faces flush with the mating surfaces before fastening to ensure smooth pivot action. Pre-drilling pilot holes is recommended to prevent splitting in wood substrates. The hinge can be cut to a shorter length using a hacksaw or metal shear if the application requires a length under 48 inches.
