The NRH 4201-140 is a premium-grade Spring Handle, proudly manufactured by NRH Box Hardware with a legacy since 1996.

The handle integrates a high-tensile spring and a comfortable black rubber grip for secure, non-slip operation. It provides a reliable grip for carrying and automatically retracts to a flush, space-saving position when released. With an impressive 490N (50kg) tensile load and a net weight of 209g, it is built for demanding industrial, transport, and military applications.

Primary Applications

This robust handle is designed for securing and providing reliable access to premium enclosures:

Heavy-Duty Flight & Transport Cases: ATA cases, road cases, and military transport boxes for sensitive equipment.
Professional Industrial Toolboxes: Large rolling tool chests and field service kits for heavy tools.
Industrial & Electrical Cabinetry: Access doors on control panels, server racks, and machinery enclosures.
Marine & Outdoor Equipment: Cases requiring the superior corrosion resistance of SUS 304 stainless steel.

How It Works (Operating Principle)

The handle operates on a reliable spring-loaded mechanism. To use, pull the handle up; it extends to a stable working angle for carrying. To store, simply release it. The internal spring automatically retracts the handle, folding it completely flat against the mounting surface for a safe, low-profile design.
