Engineered for maximum security in the most demanding environments, the NRH 5616-380 and 5617-210 represent the pinnacle of heavy-duty adjustable toggle latch design. As detailed in the provided technical drawings and specifications, these latches are built from solid iron with a protective blue zinc plating, offering a robust combination of immense strength and essential corrosion resistance. Their defining feature is the wide adjustment range, allowing for versatile installation across panels and doors of varying thicknesses – a critical solution for custom industrial equipment and standardized transport units.
The 5616-380 is engineered as an ultra-heavy-duty solution with a staggering 1200kg load capacity, weighing a substantial 1147g, and offering an adjustment from 380mm to 400mm. In contrast, the 5617-210 provides formidable strength for heavy applications with a 2940N (≈300kg) tensile load, a weight of 300g, and a versatile adjustment range of 186.7mm to 217mm. This range makes them indispensable for applications where a secure, rattle-free seal is non-negotiable.
Product Spotlight: The Adjustable Heavy-Duty Solution
The NRH 5616-380 and 5617-210 are designed to solve the challenge of securing large, heavy access points where precision fit is crucial for safety and performance. The integrated adjustment screw allows for fine-tuning the latch’s reach, ensuring a perfect, tensioned closure that eliminates gaps and resists vibration-induced loosening. This capability is vital for maintaining the integrity of protective enclosures and ensuring safe transport of heavy cargo.
Technical Specifications & Core Features
