The 3M™ QSLV-M series cold shrink quick splice kit adheres to a one-of-a-kind 3-core system. Simply place the sleeve on a connector and remove 2 of the cores to start splicing. The last core is used to support the structure of the sleeve itself. The factory expanded tubular sleeve features waterproof sealing mastic tape on each end. This kit is size-configured to adapt to differences in connector sizes, as well as to prevent damage to the seal and insulating aspects. This kit is rohs 2011/65/EU compliant and ANSI Certified.
