{"product_id":"west-penn-452bk0500","title":"West Penn 452BK0500 22 AWG Shielded Miniature Audio Cable CMR","description":"\u003cp\u003eThe West Penn 452BK0500 is a 22 AWG, 2-conductor miniature shielded audio cable designed for systems integrators, low-voltage contractors, and installed audio professionals who need a reliable, code-compliant solution for in-wall signal distribution. Its CMR (Communications Riser) NEC rating satisfies riser-space installation requirements without the cost of plenum-rated cable, making it the practical choice for most commercial and institutional AV installs.\u003c\/p\u003e\u003cp\u003eWith a 100% aluminum polyester foil shield plus a 24 AWG tinned copper drain wire, this cable delivers the interference rejection required for clean line-level audio in electrically noisy environments such as conference rooms, classrooms, houses of worship, and retail audio systems. Twisted-pair construction further reduces susceptibility to induced noise across long runs. ASTM tinned copper conductors resist oxidation over the life of the installation, preserving low-resistance continuity on permanent runs where re-termination is not practical.\u003c\/p\u003e\u003cp\u003ePolypropylene insulation and a PVC outer jacket provide the physical durability expected in a permanently installed cable. Supplied on a 500-foot spool, the 452BK0500 is sized for mid-scale projects where a full 1,000-foot spool would create waste, giving integrators better material efficiency on single-zone or multi-drop installations.\u003c\/p\u003e","brand":"West Penn Wire (Belden, Inc.)","offers":[{"title":"Default Title","offer_id":52450797027512,"sku":"141570","price":104.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/141570_WESTPEN-452BK0500_ALT01sqr.jpg?v=1783609383","url":"https:\/\/soundpro.com\/products\/west-penn-452bk0500","provider":"SoundPro","version":"1.0","type":"link"}
