Numatics™ Series NRL Rod Locks
Series NRL Rod Locks
The Numatics Series NRL is a generation of linear, static locking devices that achieve new levels of performance.
The spring-engaged, air-released devices supplement air cylinders and guide rods for holding in power-off/e-stop situations. High clamping forces ensure positive holding with minimal air required for release. Holding forces can be increased by stacking multiple rod locks together. The NRL Series´ design is sealed for use in harsh environments and features a natural brushed aluminum finish or a corrosion-resistant, black anodized finish. It can be used with Emerson´s Numatics NFPA and ISO interchangeable cylinder lines.
