5106-39 Spring Toggle Latch, 304 Stainless Steel, Panel Fastener

NRH 5106-39 Toggle Latch - Stainless Steel, Vibratory Polish, Spring Assisted, 15kg Load

The NRH 5106-39 is a durable, spring‑assisted toggle latch built for secure panel fastening in demanding environments. Manufactured from 304 stainless steel with a smooth vibratory polish, it offers excellent corrosion resistance, a clean satin appearance, and burr‑free edges. The integrated spring mechanism ensures smooth, controlled action during manual engagement and release, providing a premium tactile feel. The over‑center toggle delivers a positive, vibration‑resistant lock with a 147N (15kg) tensile load. Weighing only 10g and with a compact overall height of approximately 39mm, it is ideal for small to medium‑sized enclosures where both strength and corrosion resistance are critical. Clear “NRH” branding ensures authenticity and quality.

As a product of NRH Box Hardware (specialist since 1996), this latch is manufactured under an ISO 9001 certified system. Regarding international compliance (SGS, REACH, RoHS, SVHC), these standards can be supported based on customer requirements - contact us for details. OEM/ODM services are available for custom hole patterns, lever lengths, or logo engraving. Full 2D/3D CAD models available upon request.

Key dimensions: overall height 39mm, with 4×Ø3mm mounting holes (refer to engineering drawing for exact hole pattern and complete dimensional data).

Why 304 Stainless Steel + Vibratory Polish?

304 stainless steel is the industry standard for corrosion resistance, ideal for applications exposed to moisture, washdowns, or mild chemicals. Unlike plated steel, it retains its rust resistance even if scratched. The vibratory polish process uniformly deburrs and smooths the metal, creating a satin surface that is free of sharp edges, safe to handle, and easy to clean. The integrated spring assist enhances operation by:

• Providing smooth, consistent engagement and release
• Delivering crisp tactile feedback (“snap”) when fully locked
• Reducing friction and wear on pivot points, extending service life
• Preventing abrupt motion that could pinch fingers

Primary Applications - Where Durability Meets Smooth Operation

• Instrument cases & electronic housings - test equipment, portable devices, control modules
• Electrical enclosures & cabinets - industrial control boxes, network cabinets, outdoor‑rated enclosures
• Food & beverage or marine equipment - environments with frequent washdowns or moisture exposure
• Toolboxes & transport cases - professional tool chests, flight cases, sample boxes

How It Works - Spring‑Assisted Over‑Center Toggle

The latch operates on a classic over‑center toggle mechanism enhanced by an internal spring. When you push the lever down, the spring helps draw the hook past the center point, creating a self‑locking hold that resists vibration and accidental opening. To release, lift the lever; the spring again provides smooth, controlled motion, preventing sudden snap‑back. This design ensures positive engagement every time with minimal user effort. The 304 stainless steel construction and vibratory polish guarantee consistent performance for thousands of cycles, even in humid or corrosive environments.

Key Advantages

• Spring‑assisted operation - smooth, controlled open/close with crisp tactile feedback
• 15kg (147N) holding force - reliable for medium‑duty doors, lids, and panels
• Lightweight (10g) and compact (39mm height) - fits tight spaces, adds negligible mass
• 304 stainless steel with vibratory polish - superior corrosion resistance, satin, burr‑free
• Tool‑free, one‑handed operation - quick access, no special tools required
• Precision mounting - 4×Ø3mm holes on a stable base pattern (refer to drawing)
• OEM/ODM ready - custom hole sizes, lever shapes, logo engraving
