The NRH R4201-110 is a precision-engineered spring handle from NRH Box Hardware, a trusted manufacturer since 1996. Designed for durability and a clean, modern aesthetic, it is constructed from SUS 201 stainless steel with a smooth Brushing surface finish. The handle is equipped with a comfortable black rubber grip sleeve for secure, non-slip, and ergonomic operation. Its reliable spring mechanism provides smooth extension for carrying and ensures automatic retraction to a flush, space-saving position when released. Weighing 127g with a robust 294N (30kg) tensile load, it is built for dependable performance in demanding industrial and commercial applications. The product proudly displays the “NRH” brand stamp and is manufactured in full compliance with international standards, including ISO 9001:2008, SGS, REACH, SVHC, and RoHS. We offer comprehensive OEM/ODM services to meet specific project requirements.
Primary Applications
This handle is the ideal solution for secure and easy access to a wide array of professional enclosures:
-
Industrial Control Cabinets & Consoles: Doors and access panels on PLC cabinets, server racks, and machinery housings.
-
Professional Tool & Equipment Storage: Heavy-duty toolboxes, mobile workshop carts, and field service kits.
-
Instrument & Technical Cases: Protective transit cases for portable testing equipment, measurement devices, and sensitive instruments.

How It Works (Operating Principle)
The handle operates on an intuitive and reliable spring-loaded mechanism. To use, simply pull the rubber-gripped handle upward; it will extend smoothly and lock into a stable, ergonomic position ideal for carrying or opening. To store, release your grip. The high-quality internal spring automatically and swiftly retracts the handle, allowing it to fold down completely flat against the mounting surface. This design guarantees a secure hold when needed and maintains a sleek, low-profile, and snag-free appearance when not in use.
