The NRH 4201-120 is a heavy-duty spring handle engineered for reliable, daily use on professional equipment cases and enclosures. Manufactured from durable 304 Stainless Steel (SUS304) with a smooth Vibratory Finishing, it combines corrosion resistance with a clean, easy-to-maintain surface. The handle is fitted with a comfortable black rubber grip for a secure, non-slip hold. Its defining features include a practical ~80° working angle for stable carrying and an automatic spring-return mechanism that folds the handle flat when released. With a net weight of 161g and a robust 343N (35kg) tensile load, it is built to last. As a product of NRH Box Hardware, a trusted manufacturer since 1996, it is backed by ISO 9001, SGS, REACH, and RoHS certifications, with OEM/ODM services available.
Primary Applications
This handle is the practical choice for securing and accessing a wide array of industrial and transport containers:
-
Professional Tool & Equipment Storage: Heavy-duty rolling tool chests, mobile service carts, and field technician cases that are frequently moved.
-
Industrial & Electrical Cabinets: Doors and drawers on control panels, server racks, and modular industrial enclosures.
-
Transportation & Logistics Cases: ATA flight cases, shipping containers, and protective transit boxes for instruments and gear.

How It Works (Operating Principle)
The handle operates on a straightforward spring-loaded principle. To carry, pull the handle up; it smoothly extends to the ~80° working stop, providing a stable and ergonomic grip. To store, simply release it. The internal spring automatically retracts the handle, allowing it to fold down completely flush against the surface, ensuring a space-saving and snag-free profile.
