Featuring 3 independent 18 AWG conductors, this cable is UL-rated as CMR (Communications Riser), making it safe and compliant for vertical installations between floors, inside riser shafts, or within walls. Utilizing a solid-core layout, it offers enhanced structural integrity, minimal signal attenuation over long distances, and stable terminations.\u003c\/b\u003e\u003c\/p\u003e\n\u003ch4 data-path-to-node=\"2\"\u003eKey Features of Belden 5321UE\u003c\/h4\u003e\n\u003cul data-path-to-node=\"3\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,0,0\"\u003e\u003cb data-path-to-node=\"3,0,0\" data-index-in-node=\"0\"\u003eHeavy-Duty 18 AWG Wire Gauge:\u003c\/b\u003e Built with larger 18 AWG conductors to support longer cable runs and higher current demands with minimal voltage drop, making it ideal for critical low-voltage power and signaling pathways.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,1,0\"\u003e\u003cb data-path-to-node=\"3,1,0\" data-index-in-node=\"0\"\u003eCMR Riser Safety Rating:\u003c\/b\u003e Certified with a UL 1666 Riser rating.
