Made from cross-linked polyolefin with a 3:1 shrink ratio, this sleeve expands to a minimum diameter of 3 inches and recovers to a maximum diameter of 1 inch, covering cable sizes from 600 to 1250 KCMIL. Rated for 600 volts and a temperature range of -55 to 110 degrees C, it delivers reliable insulation, moisture exclusion, and mechanical protection. Licensed electricians and utility crews specify this sleeve for underground, overhead, and indoor applications where a thick-wall solution is required.\u003c\/p\u003e\n\u003cp\u003eThis sleeve is suited for residential service entry points, commercial switchgear installations, and utility distribution work. Approved applications include insulating secondary splices, service relocation, dig-in repairs, and sheath repairs. Its cross-linked polyolefin construction makes it equally effective indoors, outdoors, or in overhead configurations. Each case contains 5 sleeves, each 48 inches in length, giving crews enough material to handle multiple repairs or splices from a single stock unit. The black color also aids UV resistance in exposed overhead runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3:1 shrink ratio covers cable OD range of 2.25 to 1.2 inches with a single sleeve size\u003c\/li\u003e\n  \u003cli\u003eHeavy wall construction resists puncture and abrasion damage in direct-burial and overhead environments\u003c\/li\u003e\n  \u003cli\u003eCross-linked polyolefin material resists acids, alkalies, and UV exposure\u003c\/li\u003e\n  \u003cli\u003eRated -55 to 110 degrees C for wide temperature service including cold-climate outdoor installations\u003c\/li\u003e\n  \u003cli\u003eBonds to a wide variety of substrates for a reliable, weatherproof seal\u003c\/li\u003e\n  \u003cli\u003eRoHS compliant; approved to UL 486-D and CSA standards\u003c\/li\u003e\n  \u003cli\u003eCountry of origin: United States\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 600 to 1250 KCMIL cables with an outer diameter of 1.2 to 2.25 inches.

De-energize and lockout-tagout all circuits before applying the sleeve. A heat gun or torch delivering uniform heat should be used to shrink the sleeve evenly from the center outward to prevent air pockets. Follow NFPA 70 (NEC) requirements for insulation ratings and splice protection applicable to the circuit voltage and environment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Heat Shrink\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWall Type\u003c\/strong\u003e: Heavy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cross-Linked Polyolefin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShrink Ratio\u003c\/strong\u003e: 3:1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: -55 to 110 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShrink Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Expanded Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Recovered Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCable Outer Diameter Range\u003c\/strong\u003e: 1.2 to 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCable Size\u003c\/strong\u003e: 600 to 1250 KCMIL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 48 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackaging Quantity\u003c\/strong\u003e: 5 pieces per case\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 10.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 51.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 9.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 9.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL 486-D, CSA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoHS Compliant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: United States\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: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: IT3.000BK48IN-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51283911999794,"sku":"IT3.000BK48IN-S","price":171.67,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279317.jpg?v=1781063076","url":"https:\/\/voomisupply.com\/products\/3m-it3-000bk48in-s-heat-shrink-cable-sleeve-48-in","provider":"Voomi Supply","version":"1.0","type":"link"}
