Dottie RC4 Nut, 5/16"-18 Rod Coupling Nut

For fast, reliable rod extensions in security, surveillance and low-voltage installations, the Dottie RC4 5/16-18 Rod Coupling Nut is the professional choice. This coupling nut joins two pieces of threaded rod—vertically or horizontally—so you can extend camera mounts, antenna masts, conduit supports, and rack assemblies without compromising strength. Crafted from carbon steel with a zinc-plated finish, the RC4 resists corrosion in indoor and outdoor environments while delivering dependable mechanical performance. The standard 5/16-18 threading and a compact 0.87" length make it compatible with common threaded rod sizes used across CCTV, monitoring, access control and networking mounting systems. Supplied in a practical pack of 50, it streamlines procurement for large deployments and service crews. Whether you’re assembling surveillance poles, reinforcing structural supports or completing rack installations, the Dottie coupling nut provides a sturdy, economical solution. Add the RC4 to your next security or networking project to ensure secure rod joins and minimize on-site delays.
