Constructed from cross-linked polyolefin with a 3:1 shrink ratio, this sleeve shrinks at 250 degrees F to form a tight, durable seal over cable diameters ranging from 0.4 to 0.88 inches. The minimum expanded diameter is 1.1 inches and the maximum recovered diameter is 0.37 inches. At 9 inches in length, each sleeve provides substantial coverage for splice insulation, sheath repairs, and service relocation work. Licensed electricians and utility technicians are the primary installers of this product.\u003c\/p\u003e\n\u003cp\u003eThis sleeve is suited for a broad range of electrical repair and protection tasks including insulating secondary splices, dig-in repairs, sheath repairs, and relocation of service conductors. It accommodates cable sizes from 2 AWG to 4\/0 AWG, making it practical across residential and commercial service work as well as utility and underground applications. The black color and UV-resistant material make it appropriate for exposed outdoor installations. Each case contains 100 pieces, supporting high-volume field or shop use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3:1 shrink ratio covers a wide range of cable diameters with fewer sleeve sizes\u003c\/li\u003e\n  \u003cli\u003eHeavy wall construction resists puncture and abrasion damage\u003c\/li\u003e\n  \u003cli\u003eCross-linked polyolefin material resists acids, alkalies, UV exposure, and weathering\u003c\/li\u003e\n  \u003cli\u003eRated to 600 volts with UL 486-D and CSA approvals\u003c\/li\u003e\n  \u003cli\u003eTemperature rated from -55 to 110 degrees C (-67 to 230 degrees F)\u003c\/li\u003e\n  \u003cli\u003eRoHS compliant; bonds to a wide variety of substrates\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with cable sizes 2 AWG through 4\/0 AWG with outer diameters between 0.4 and 0.88 inches.
