NRH 5807-60-1 Square Toggle Latch – SUS201 Brushed Finish Economical

NRH 5807-60-1 Square Toggle Latch - SUS201 Stainless Steel, Brushed Finish, 40kg Load, Economical, No Safety Lock

For aviation cases, power supply boxes, and industrial machinery requiring reliable locking without accidental opening prevention, stainless steel models with safety locks may be over‑specified and costly. The NRH 5807-60-1 is a square toggle latch from the 5807 series featuring a longer hook design. Manufactured from SUS201 stainless steel with a brushed finish, it offers a uniform linear texture, wear resistance, and a matte metallic appearance. This model has no safety lock - relying solely on the over‑center self‑locking mechanism for simple, quick operation. Weighing just 39g with a 392N (approx. 40kg) load capacity and an overall length of approximately 60mm, it is compact and lightweight. Mounting holes are 2×Ø3.2mm for simple surface mounting. The extended hook design of the 5807 series spans the curved rims of insulated buckets and round containers, providing deeper, more secure engagement. Suitable for aviation cases, heavy‑duty luggage, firefighting cases, trunks, import/export wooden crates, machinery, instruments, marine equipment, medical boxes, power supply enclosures, and filters. Clear NRH branding and heritage since 1996 assure quality.

Manufactured under ISO 9001. REACH, RoHS compliance available on request. OEM/ODM modifications (finish, logo) welcome. 2D/3D CAD drawings supplied.

Key dimensions (see drawing): overall length approx. 60mm, mounting holes 2×Ø3.2mm. Refer to engineering drawing for other dimensions.

1. Material & Finish

SUS201 Stainless Steel
SUS201 austenitic stainless steel (Cr 16-18%, Mn 5.5-7.5%) offers higher strength and work hardening than SUS304 at lower cost. Suitable for applications requiring moderate corrosion resistance with balanced strength and economy.

Brushed Finish
The brushed finish creates a uniform linear texture with a matte metallic luster. It is wear‑resistant, hides minor scratches, and does not reflect light - ideal for outdoor, industrial, and low‑glare applications.

2. 5807 Series Long Hook Design

This product belongs to the NRH 5807 series, featuring an extended hook design. Compared to standard square latches, the longer hook spans the curved rims of insulated buckets, food drums, and chemical barrels, providing deeper, more secure engagement - especially suited for round or curved container edges.

3. Working Principle

This latch uses a classic over‑center four‑bar toggle mechanism with no safety lock:

• Closing: Hook the latch onto the strike plate, then press the handle down. Past dead center, the mechanism self‑locks, generating constant clamping force that resists vibration.
• Opening: Lift the handle to release the over‑center lock. Without a secondary lock, operation is direct and fast - ideal for frequent opening/closing where accidental release prevention is not required.

4. Applications & Industry Examples

• Aviation flight cases / road cases - Over‑center self‑locking keeps lids closed under transport vibration; long hook fits rounded corners.
• Insulated buckets / food drums / chemical barrels - 5807 series long hook optimized for curved rims; SUS201 provides corrosion resistance; brushed finish easy to clean.
• Power supply boxes / electrical enclosures - Economical stainless steel meets basic rust prevention; no safety lock for quick operation.
• Firefighting cases / emergency response boxes - Quick opening without extra release steps, suitable for emergencies.
• Heavy‑duty luggage / industrial equipment cases - 40kg load capacity sufficient for heavy toolboxes.
• Machinery guards / access doors - High‑frequency opening/closing; over‑center lock resists vibration; no safety lock reduces steps.
• Instrument cases / laboratory equipment - Brushed finish resists fingerprints, clean appearance.
• Marine equipment boxes - SUS201 provides basic corrosion resistance for coastal environments.
• Import/export wooden crates - Quick open/close for frequent customs inspection.

5. Installation & Maintenance

• Drill holes per drawing. Secure with M3 screws through 2×Ø3.2mm holes; add washers inside panel.
• Test open/close after installation - the over‑center snap should be crisp.
• Periodically inspect for rust or deformation; lubricate pivot points lightly.
• Clean brushed surface with a soft cloth; avoid scratching.
