NRH 3101-180s Safety Toggle Clamp - SUS304 Stainless Steel, Vibratory Finish, 300kg Clamping Force, Adjustable Length, Safety Lock

The NRH 3101-180 is a professional-grade safety toggle clamp designed with a reliable locking mechanism that prevents accidental release during critical operations. Featuring a distinctive blue handle for easy identification and operation, this clamp is engineered from SUS304 stainless steel with a vibratory finishing surface that provides both durability and corrosion resistance. As a product from NRH Box Hardware, a specialist manufacturer since 1996, this safety clamp combines quick‑release functionality with secure locking capability, making it ideal for applications where workpiece security is paramount.

Regarding international compliance (ISO 9001, SGS, REACH, RoHS, SVHC), 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 for custom applications.

Key features: adjustable clamping length from 153mm to 180mm, clamping force 2942N (300kg), weight 249g, mounting holes 4 × Ø6.5mm. Detailed dimensions as per drawing: 122mm, 45mm, 24mm, 16.8mm, 5.3mm, 25.7mm, 44.3mm, 2.7mm, 33mm, 22.3mm, 11.5mm.

Primary Applications

This safety locking clamp is specifically designed for applications requiring both quick operation and secure holding:

• Industrial equipment and machinery: Securing components in welding jigs, fabrication fixtures, CNC machine guards, and assembly stations where accidental release could be hazardous
• Transport and shipping cases: Providing locked security for ATA cases, flight cases, instrument transport boxes, and valuable cargo containers
• Military and field equipment: Ensuring tamper‑resistant closure for military gear cases, communication equipment boxes, and tactical storage containers
• Automotive and manufacturing: Used in production fixtures, quality control stations, and automotive repair jigs requiring secure workpiece positioning
• Woodworking and carpentry: Ideal for woodworking fixtures, clamping stations, and assembly jigs where locked position prevents workpiece movement

How It Works - Operating Principle

This clamp operates on an over‑center toggle mechanism with a safety locking feature. The blue handle serves as the operational lever - pushing it down engages the clamping arm and activates the over‑center locking action. The unique safety lock mechanism prevents the handle from being accidentally lifted once engaged, ensuring the workpiece remains securely held. To release, the lock must be deliberately disengaged before lifting the handle, providing an additional layer of operational safety.
