3M™ 8560 Series QT-III Three Core Cold Shrink Cable Silicone Breakout Boots are a series of open-ended molded rubber sealing assemblies that are factory expanded and mounted on removable inner supporting plastic cores. They are supplied for field installation in a pre-stretched condition.
The supporting cores are removed after the seal has been positioned for installation around the breakout area of a 3/C (three conductor) cable. Core removal allows the silicone rubber boot to shrink down to a pre-determined diameter, creating an environmental enclosure for indivudal cable phase legs and the overall cable jacket.
