The NRH 8133-51 is a specialized 90-degree lid support hinge, meticulously engineered for small wooden boxes, chests, and cases. Its primary function is to securely prop open a lid at a perfect right angle, providing stable, hands-free access to the contents within. This compact hinge is crafted from iron and finished with a durable chrome plating, ensuring reliable performance and a clean, classic appearance that complements wood finishes. Weighing a mere 24g with a reference load capacity of 8kg (for two hinges installed), it provides ample strength for typical small box lids without overwhelming delicate constructions.
Precision engineering is detailed in the provided technical illustration. Key dimensions include a total width of 51mm, a height of 46.6mm, and a compact form factor. The design incorporates 4 x Ø4mm mounting holes with Ø7mm counterbores, enabling discreet and secure flush-mounting on wooden surfaces. Critical internal dimensions, such as 7.6mm and 16.5mm, define the robust pivot geometry that delivers the reliable 90-degree stop function. The data serves as a critical reference for seamless integration into your box design.
Product Spotlight: The Perfect Lid Prop for Wooden Boxes
The 8133-51 is purpose-built for box makers and craftsmen. Its integrated mechanical stop ensures the lid opens precisely to 90 degrees and remains firmly in that position. This prevents the lid from falling backward, protecting its finish and hinges, while keeping it safely out of the way for full, two-handed access to the box’s interior. The chrome plating offers a layer of protection and a timeless look that enhances both traditional and modern box designs.
