This cable is designed to carry structured data cabling through vertical runs between floors in commercial and residential buildings while meeting the fire-propagation resistance requirements of a riser-rated installation. It suits environments where the cable must transition from exterior conduit entry points into interior riser pathways, making it a practical choice for a single cable run without mid-point termination or cable swaps.\u003c\/p\u003e\n\u003cp\u003eThis cable is suited for structured wiring projects in commercial office buildings, multi-unit residential properties, and light industrial facilities. It supports horizontal and vertical distribution runs where both outdoor exposure and riser-rated performance are required. Network technicians and low-voltage electricians typically specify this cable when routing from exterior entry points, equipment enclosures, or rooftop equipment down through interior building risers to patch panels or network equipment rooms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCategory 5e performance supporting standard Ethernet data transmission applications\u003c\/li\u003e\n  \u003cli\u003eCMR (Riser) fire rating meets vertical flame propagation requirements for in-building riser runs\u003c\/li\u003e\n  \u003cli\u003eIndoor and outdoor dual-rated construction for runs that transition between exterior and interior environments\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit (EA), allowing quantity-specific procurement for project needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a CMR-rated Cat 5e replacement or new-install cable suitable for riser pathway applications in standard structured cabling systems that accept Category 5e specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed low-voltage technician or electrician familiar with NEC Article 800 requirements governing communications cables in riser applications. Verify that the riser pathway is free of obstructions and that all cable bend-radius minimums are maintained throughout the run. Do not exceed the cable pull-tension rating during installation, and secure all outdoor segments in conduit or weatherproof channels as required by local code. Terminate only with Cat 5e-rated connectors, patch panels, or keystone jacks to maintain signal integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCable Category\u003c\/strong\u003e: Cat 5e (CAT5 Riser)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFire Rating\u003c\/strong\u003e: CMR (Communications Multipurpose Cable, Riser)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Environment\u003c\/strong\u003e: Indoor and Outdoor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each (EA)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Unit\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SUPERIOR ESSEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 51-240-E1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUPERIOR ESSEX","offers":[{"title":"Default Title","offer_id":51984666722610,"sku":"51-240-E1","price":632.7,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b4f62d920a2b150d0dbfe9b109e8209.jpg?v=1789984942","url":"https:\/\/voomisupply.com\/products\/superior-essex-51-240-e1-cat-5e-cmr-network-cable","provider":"Voomi Supply","version":"1.0","type":"link"}
