The NRH R4201-140 is a robust heavy-duty spring handle designed for maximum strength and daily reliability. As detailed in the specifications, it is manufactured from durable SPCC steel with a bright and protective Chrome Plating finish. The handle features a comfortable black rubber grip for a secure, non-slip hold. Its high-tensile spring mechanism ensures smooth extension for carrying and provides automatic retraction to a flush, space-saving position when released. Weighing 190g with an impressive 392N (40kg) tensile load, it is engineered for the most demanding industrial and transport applications. Proudly manufactured by NRH Box Hardware with a heritage since 1996, this product complies with ISO 9001:2008, SGS, REACH, SVHC, and RoHS standards. OEM/ODM services are available.
Primary Applications
This handle is built for securing and providing reliable access to heavy enclosures:
-
Server Racks & Data Cabinets: Heavy doors on server racks, network cabinets, and communication enclosures.
-
Industrial Toolboxes & Machinery: Large rolling tool chests, welding equipment cases, and heavy-duty service kits.
-
Professional Flight & Road Cases: Extra-large ATA cases and transit boxes for broadcasting and touring equipment.

How It Works (Operating Principle)
The handle operates on a powerful spring-loaded mechanism. To use, pull the rubber-gripped handle upward; it extends smoothly to a stable, locked position for carrying. To store, simply release it. The internal spring automatically and firmly retracts the handle, folding it completely flat against the mounting surface for a safe, streamlined profile.
