Its CMR (Riser) rating and UL\/cUL listing make it a compliant choice for vertical building runs where fire code adherence is required on every pull.\u003c\/p\u003e\u003cp\u003eSystems integrators and low-voltage contractors will find this cable well-suited for intercom audio wiring, line-level signal distribution, background music systems, and paging infrastructure where shielding is critical to maintaining signal integrity across long runs. The 100% aluminum polyester foil shield with a tinned copper drain wire suppresses electromagnetic interference without adding bulk, keeping terminations clean in densely populated equipment rooms and junction boxes.\u003c\/p\u003e\u003cp\u003eCompared to unshielded alternatives, the overall shield and twisted-pair geometry provide a meaningful advantage in environments with HVAC motors, fluorescent lighting, and other noise sources common to commercial installs. The PVC jacket and polypropylene insulation hold up to the mechanical demands of conduit pulls, and the 1000-foot bulk spool format suits larger projects where per-foot cost and continuous run length both matter.\u003c\/p\u003e","brand":"West Penn Wire (Belden, Inc.)","offers":[{"title":"Default Title","offer_id":52445346726072,"sku":"11316","price":235.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/11316_WESTPEN-293BK1000_ALT01sqr.jpg?v=1783609262","url":"https:\/\/soundpro.com\/products\/west-penn-293bk1000","provider":"SoundPro","version":"1.0","type":"link"}
