The NRH 8131-48 is a versatile, medium-duty hinge engineered to provide reliable and stable pivoting for a variety of cases and doors. Its core function is enhanced by a practical 90-degree opening stop, which allows lids and doors to be held securely in the fully open position. This feature is particularly valuable for applications requiring hands-free access to the contents of a case or unobstructed access to a cabinet interior.
Manufactured from iron and finished with a durable chrome plating, this hinge offers good corrosion resistance and a clean, metallic appearance. With a product weight of 51g and a load capacity of 6kg (reference value for two hinges installed longitudinally), it is well-suited for supporting the lids of loaded cases and medium-weight doors. The hinge design ensures smooth operation and the 90-degree stop provides stability when open.
Based on the comprehensive technical data, the hinge is designed for precise integration. Key dimensions include a total length of 48.5mm, a leaf width of 32.5mm, and a material thickness of 2mm. The mounting pattern features Φ4.3mm holes on standardized centers, specifically 34.5mm apart, allowing for secure and straightforward installation. Other critical dimensions, such as the 20mm and 44mm measurements, define the pivot geometry and the 90-degree stop mechanism.

Product Spotlight: The Value of a 90-Degree Stop
The integrated 90-degree opening stop is the defining feature of the 8131-48. This mechanical function prevents the hinge from opening beyond 90 degrees, ensuring that a lid or door remains stably in the fully open position. This eliminates the need to manually hold the lid open while working, prevents it from swinging closed accidentally, and protects adjacent walls or surfaces from impact. The chrome-plated finish ensures smooth operation of this stop mechanism over time.
