Why choose our 18/2 CL3R Shielded Cable?
 
Superior Signal Integrity: The integrated shielding protects your data and audio signals from electromagnetic interference (EMI) and external "noise," ensuring a clear, consistent connection for your security cameras, alarms, and intercom systems.
Flexible & Easy to Install: The stranded copper (CU) conductors make this cable more flexible than a solid-core alternative. It's easy to pull through walls, around corners, and in conduits, saving you time and effort on every project.
Safety Rated for Riser Applications: The "CL3R" rating means this cable is certified for installation in "riser" spaces, such as between floors in a building, meeting critical fire safety codes without the need for conduit.
Versatile and Dependable: With 500 feet on a convenient spool, you have plenty of length for large-scale residential or commercial installations. Ideal for low-voltage applications like:
Security Cameras and Alarm Systems
Access Control and Intercoms
Audio Speakers and Public Address Systems
Power-Limited Controls
 
Don't let a cheap cable jeopardize your system's performance. Invest in the professional-grade cable trusted by experts.
