Stainless Steel Spring Handle with 80° Stop | Auto-Return for Tool Cases

NRH 4201-120 Spring Handle - SUS304 Stainless Steel, Vibratory Finish, Rubber Grip, 35kg Load, 80° Angle, Auto Return

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, this handle is produced under a certified quality management system. Regarding international compliance (ISO 9001, SGS, REACH, RoHS), we can support these standards based on customer requirements and applicable costs - please contact us for specific certification needs. OEM and ODM services are available.

Key dimensions include an overall length of 122mm, hole spacing of 85mm, grip diameter of approximately 16mm, with 4x Ø6mm mounting holes.

Primary Applications

• Professional tool and equipment storage: Heavy‑duty rolling tool chests, mobile service carts, and field technician cases that are frequently moved
• Industrial and electrical cabinets: Doors and drawers on control panels, server racks, and modular industrial enclosures
• Transportation and logistics cases: ATA flight cases, shipping containers, and protective transit boxes for instruments and gear
• Vehicle and machinery: Access handles for truck toolboxes, construction equipment panels, and utility compartments
• Robust furniture and workstations: Pull handles for industrial workbenches and technical storage units

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.
