NRH R4201-140 Heavy Duty Spring Handle - SPCC Steel, Chrome Plating, Rubber Grip, 40kg Load

The NRH R4201-140 is a robust heavy‑duty spring handle designed for maximum strength and daily reliability. Manufactured from durable SPCC steel with a bright and protective chrome plating finish, this 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 handle is produced under a certified quality management system. Regarding international compliance (ISO 9001:2008, SGS, REACH, SVHC, RoHS), these standards can be supported based on customer requirements and applicable costs - please contact us for specific certification needs. OEM and ODM services are available.

Primary Applications

• Server racks and data cabinets: Heavy doors on server racks, network cabinets, and communication enclosures
• Industrial toolboxes and machinery: Large rolling tool chests, welding equipment cases, and heavy‑duty service kits
• Professional flight and road cases: Extra‑large ATA cases and transit boxes for broadcasting and touring equipment
• Industrial control panels: Large access doors on control and power distribution panels

How It Works - Spring‑Loaded Mechanism

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.
